I haven't heard of repeated fandoms causing matching gremlins. However, I've never personally run matching on an exchange that allows this option. One person to ask might be BridgetM, the mod of Not Ready for Prime Time (http://npt-admin.dreamwidth.org/), as she has allowed duplicated fandom requests in her exchange.
I do not think it's an issue, though, as there are several single-fandom exchanges where people divide up their offers and requests in some way and therefore require more than one use of the same fandom in each section of their sign-up.
