Why is this type of position called an "optional redouble"? Surely the
redouble is automatic. I guess the 2-ply analysis is looking ahead and
automatically doubling on the next roll so it sees no loss of equity.

That is exactly the point. No equity is lost by waiting to double. So you might want to double later - where there might be a better chance that X will make a wrong drop. Thinking like this takes up a lot of brain power better used elsewhere, though - since you have to consider before every roll, whether you have any market loosers.

BTW: I am surprised that 5-5 is not considered a market looser by gnu in this position.
