Tainan Mantis commented about this on the other thread. I would like to further address this.
First off, the Chinese character used is Guan (Stick or staff). So stick/staff (adjective) hand is the name of the technique moreover the translation stick (verb) is also valid IMHO. I will futher explan this.
"The 9th exercise you refer to is called “stick” hand. As in the 7th rigid technique from the 8 rigid 12 flexible. "
The exponent of this technique is like whirling a stick/staff with the left hand being the anchor hand and the right hand being the leverage/pivot hand). I believe 7*'s coined this technique “staff hand” as the motion of the 2 hands is remarkably resemble whirling a staff - The filing punch [re: tiao with a staff] or in some cases downward backfist [re: pi with a staff] and the hanging & straight punch [re: ti or tang with a staff ]. Except when this translated into empty hand strike the front hand becomes a strike.
"The Stick technique is done by “B”
A: right stance-right low straight punch
B: right stance-left sealing hand(pushing down type block/grab)-
right inverted straight punch(your filing punch)
A:right high block(bi sho/closing hand)
B:left lifting hand-to lift A’s high block even higher so it can’t go down,
right low straight punch"
This example is taking the inside gate while I think the outside gate works well too. As seen in this example, B’s sealing hand or rather binding/tiding hand is crucial to the technique as it is the “anchor” and controls the right side of the opponent. It is a form of trapping IMHO. However, it is not wrong to sort of chop down with the sealing hand. But then you are not tied/binded to your opponent niether. 
So not really binding but still whirling a staff [re: stylistic difference]
"Last year I opened on a thread on this specific technique, stick, because in several cases different characters were used which completely changed the meaning.
It seems that there is a difference in different schools on what this technique is.
The above method follows my teacher, Shr Zhengzhong’s, teaching as well as WHF and Luo Guangyu’s 14 roads."
I remember Sifu Carl Albright’s explanation as well on this matter. His view is that the attack is continuous and the hand doesn’t retrack. IMHO, that is part of this technique is about. Using the whirling staff hand analogy, you don’t pull/chamber your front/pivoting hand like the way you would in empty hand form while using a staff. So the 7* explanation seems to be using the whirling staff motion in describing an aggressive attack with a powerful right hand [re: rapid firing of the hands] being fast and hard. So staff hand being one of the 8 hard is reasonable.
"On looking at the older manuscripts in Ilya Profatilov’s collection, as well as some other related sources, the word “bind” is used.
They both sound similar, but “stick” and “bind” have different implications. "
The sound of binding/tiding and Stick/staff is quite similar. Binding in this case is the left hand that “ties” to the right hand (although in your example the grab might have been broken temporarily). I think Binding is using one hand to restrain one [entire] side the opponent. That is to say using one hand to manipulate the weight shifting of the foe while attack fast and hard with the other hand. You will indeed need to have a strong and tigh grip with the grab so that you are tied to your opponent [re: giving you more of a listening to his weight shifting - internal so to speak].
It would seem that all schools are indeed descibing the same technique via different approaches.
In my mind, we have gone throught 3 different ways of PM Trapping techniqus - Sealing, Stealing and Binding.
“Anyway, the stick method works very well and is comprised in many styles of MA.”
Agreed totally. 
Warmest regards
