That doesn't seem likely to be an inconsistency to me. James (and Lily) Potter were members of the Order of the Phoenix during the last war. I don't recall David Monroe being a member of that group in this continuity, but he was an active member of the opposition. It stands to reason that moderately important opposition figures would have known each other, especially since there seem to have been relatively few people actively involved in the war on either side.
Moody's wording in ch86 seems to imply the Order may not have even existed before Monroe 'died':
..."Flush of gratitude and all that," Mad-Eye Moody said sourly. "It didn't last, but at least James and Lily got a fancy title and a useless medal to take to their graves. But that's leaving out eight years of complete horror after Monroe disappeared and Regulus Black - he was Monroe's private source in the Death Eaters, we're pretty sure - was executed by Voldie. Like a dam breaking and gore flooding out, drowning the whole country. Albus bloody
