False Start?

[Suudy]

In discussions with other officials over a beer last night, we considered the following:

A has 7 on the line of scrimmage. All interior linemen have their hands on the ground. The tackles, guards, and center are all numbered 50-79.

Prior to the snap, the end A1, moves into the backfield, uncovering the tackle, A2. A2 then lifts his hand and adjusts. Then A1 moves back onto the line. All are legally set before the snap.

Is this a false start by A2? A2 is not eligible by number, but is on the end of the line. Can A2 lift his hand a shift while on the end of the line, regardless of his eligibility?
