"A conflict is 'false' when, from a particular ancestral snippet, both the left and right branches have changed to have the same contents. In some circumstances this can be treated as a clean merge; in others, it's actually an exception that needs to be dealt with. See http://revctrl.org/AccidentalCleanMerge."
