So with current order, patch 2 introduces regression that is fixed in
patch 4, is my understanding correct?

This is not the best idea because it will break bisectability. I would
recommend you to change the order and move patch #4 to the begin.

Also it would be reasonable to leave a note in patch 2 comment that it
causes regression if applied alone.
