Yes, using the feats gained by vigilante talents triggers this effect. And it's for a good reason.
It's a "use common sense" sort of rule. The problem with vigilante is that it's easy to play outside of the intended way...
Your character should be similar to how different Bruce Wayne is from Batman. Bruce seems exactly like the type of person that *couldn't be batman* because his personality is so different in his "social identity."
Even though you might be a level 11 vigilante and have 6 other feats not from vigilante talents, your social identity shouldn't seem like a good fighter... Not because he's not allowed to be, but because you're trying to draw as much attention away from the possibility that you're capable of that sort of thing, since you're trying to make it seem impossible or at least highly unlikely that you're the vigilante.
If people watch your social identity absolutely destroy someone in combat, even though you didnt use your one vigilante-talent feat, and then also there are stories of some vigilante who's maybe only slightly better at combat, they may not make that connection for sure, but they'd certainly be less surprised or dismiss the idea that you could be the vigilante...
Your social identity shouldn't be slightly worse at combat than your vigilante, your social identity should be intentionally avoiding combat, unless he can do it sneakily or make it pass as an accident or lucky... If you can't do any of these things, and you have witnesses, you should be intentionally fighting as poorly as possible while still making sure you don't die. Bruce Wayne wouldn't join the Gotham City freestyle MMA fighting tournament.
