After mulling over the original issue of being able to bail out of a 
tap/activation (when AT is *not* active, which I believe was part of the 
original intent), I did some minor re-testing of certain event 
behaviors, and it seems that things have changed subtly in recent months 
with regards to event sequences fired and the automatic capture 
(depending on the type of control). I'll do some follow-up testing, but 
it does seem that the original "only fire (click, effectively) when over 
the originally touched element" has some merit for button/link type 
controls (however, not for things like sliders, which is partly what 
confused the issue for me as that related to a previous conversation in 
another group).

In short, I may look at this afresh (both the original 3.5.2 and also 
the relationship to WCAG 2.0 3.2.1) and feed something back to the list.
