Those aren't the names that will make it into the game, thankfully - those are just the winning players.
They've always said they will negotiate the henchmen names with the winners, and just make up their own ones if the player suggestions till aren't good enough.

Of course the bigger controversy is that the contest rules claimed that the entries had to be original and robust - stressed further by dev posts on the forums - only for the live team to then turn around and pick the least original and least functional entries imaginable.
Seriously; a number of those builds are quite literally copy & pasted from PvX (the Guild Wars build wiki), and almost every black-listed skill (the ones AI sidekicks won't use/can't use right) appears in a winning build.

It's pretty much the biggest triple-whammy of "competition FAIL" imaginable:

* The henchmen implemented will be - on the whole - completely worthless.

* The loyal-est/most enthusiastic players have been slapped in the face, as everyone who spent weeks planning & testing original/AI-appropriate builds lost to copy & pasters and people simply entering their Human builds.

* Anet themselves implemented new 'build capture' technology to take entries and report that they have spent week sifting the 30,000 entries - colossal investment from such a small team when the outcome could have peen achieved spending 15 minutes on PvX.

In perspective of course this is an inconsequential blip at this point in GW1s lifecycle, but it still deserves to go down in the annals of MMO infamy as an example of promotion gone bad.
