PSK or No PSK?

[BayouUmp]

This question is on our state exam and wanted to get opinion from the board.

"Third and 9 from A’s 40. QB A2 takes the snap and scrambles. While A2 is in possession behind the neutral zone, B2 holds A3 at B’s 49. A2 eventually quick kicks by punting deep. The punt rolls to R’s 25 where it is eventually blown dead since no players are attempting to recover. Ruling: If accepted, A will play a first and 10 at the 50. (True or False)"

Why would/would not this be a PSK foul? Does a scrimmage kick have to start with a scrimmage kick formation? The foul occurred before the kick crossed the ENZ, but I didn't think that was a requirement of PSK (according to 2.16.2.g) although the ruling in Case book 10.2.1 Sit D seems to indicate it.
