Not sure what you mean, unless it is the fact that some breakers switch on one way while adjacent ones have been put in the other way round so switch on the other way. Not necessarily going to cause a problem but it does mean that if someone has to isolate a circuit they may be switching it on, not off. If they do the right thing and check it is dead they will soon find out (hopefully using a tester and not their finger....)
