This goes into the philosophical, but if it's broken, it's broken, doesn't exist any more. Why would the other party be bound to it?
Granted, the rules don't make that very clear.
However, you can also set parameters for how it works to choose the role such blood magic plays in your games. If the other party has to stick to it, it's really a two-sided sword, or be used for gritty effects such as someone swearing an oath with the intention to violate it, attacking the other and accepting the wound believing the other guy wouldn't strike back... ;D
Best kaer anywhere.
