Yes, but this raises more questions than it answers!  I guess we'll need 
to wait for dbaron's post to the mailing list, but the obvious first 
question is whether calculating the hypothetical position with respect 
to the parent block is equivalent to dropping the need to perform the 
"second calculation" in 9.5.2 (and if so, the spec should be worded as 
such rather than introducing a new formulation viz. changing the point 
of reference of the hypothetical position).

I don't have time to think about this right now, but will do in due course.
