Re: Quick question: What is a hasty pad?

Can anyone please explain to me what Brad Behn meant when he wrote the following in this old post about register key modifications to address grunting in the clarion register?

"Raised register tube and Pinocchio. This technique (it is a variation on the Hasty pad) is my favorite solution. Reset the register tube by floating it with wax so that it sits several millimeters above the body of the clarinet body...This will severely reduce register grunt and response problems because it effectively works like a shortened tube..."

Why would the register tube effectively work like a shortened tube if it is merely pulled out of the bore several millimeters? As far as the air moving through it goes, it remains just as long. I realize less tube protrudes into the bore then, but to what extent does the tube "interrupting" the bore cause response problems? From other posts on this forum, I see there seems little consensus on this question in the first place.
