As far as I know, there's no separation between PvP unlocked and PvE, so I don't see how this would make a difference >.>. The thing is, all of the unlocked skills won't be learned by your PvE characters, until you buy them or use skill tomes. The heroes from NF would be able to, though.
People on GuildWiki were saying that it doesn't, though, but it seems more like it was miscommunication... might be better to try e-mailing ANet, unless someone who's actually bought them ends up posting.
