It is definitely interesting.
That's the style of the pre-searing necromancer armor, although it could also be max-level Ascalon armor from Kaineng Center (I find it unlikely, given the level, but it's still possible). It's hard to make out exactly in the screenshot, but it certainly looks like the necromancers both have Tyrian hair styles.
Therefore I can't imagine that they are bots. It makes no sense. Why would you make a Tyrian necromancer and run it all the way from Ascalon to Lion's Arch, then to Elona, when you could make an Elonian necromancer and get them to the same point in a fraction of the time?
