Keeping the arm high like this also puts the shoulder in a weak position though, and if she is prone to over rotating then this increases the chance of a dislocated shoulder by quite a lot.
Then she'll probably just go right through to the self-nelson anyway
I agree about keeping aware yourself though. It's your responsibility to look after your partner, regardless of how much danger they are to themselves (or how much danger you think they are to themselves). It's much better to abort a move that's going badly in a dangerous way than to just hope for the best. In this case someone got hurt.
