MMs are not allowed to cross or lock the market, regardless of which ECN or MM is on the inside. When a MM locks/crosses the market it is his responsibility to take action to unlock it. I don't know why ISLD would delete orders that are crossed by other MMs. I never saw this happen myself. It could be just a design decision that ISLD will be 'nice' and step away.
