do they respond faster because all else is not held equal...so a combination of the steep HT and the shorter rake fork, plus shorter wheelbase distributing the riders weight differently make both of those statements true?
Yes it is impossible to hold all else equal. If you increase HT angle you bring the wheel in closer. To keep trail the same you decrease rake now it's in even closer still. Lengthen the TT and you change the relation of your hands to the wheel.
In practice though within the small range between 71 and 75 degrees where most bikes are I don't think the actual effect of HT angle on steering is that great. The effect of HT angle on trail and rider position ends up being much more important.
