What causes the flat spot on the rim opposite the second strike?

I am not the best to answer this question, but my thoughts would be that when the 2nd strike forced the imprint it placed sideways pressure on the blank against the collar. But that's just a guess. Perhaps something akin to the Blakesley effect.

Usually when there's a flat edge opposite the 2nd strike, it's because the edge (that's now flat) was up against a stationary "wall" in the coin press. When the second strike was struck, the "wall" kept the coin from moving in that direction causing a flat edge. I hope that makes sense.
The position of the collar matches the outline of at least the anvil die, and normally the hammer die as well. So, on this coin, if the second strike was off center the collar was over there as well. Besides, the rounded collar could not have caused a flatter spot than its arc.
