point of interruption

[Ref in PA]

I asked this in another thread that died, there were no responses. Hopefully this question won't kill this thread also.

Team B scores a basket and A1 takes the ball for an inbounds pass. A2 and B2 commit a double foul 1) Before A1 releases the ball on an inbounds pass; or, 2) After A1 releases the inbounds pass (the foul occurs as the ball is crossing mid court - does location matter of the non-touched in bounds pass matter?) but before it is touched inbounds.

Assuming Team A retains the ball, does A1 still get to run the base line if the ensuing throwin is along the endline?
