Yep. It also kind of incites enemy teams to converge on that objective.
We once had an ArenaNet employee in our guild and he would use ANet's guild to claim objectives (in particular SMC) and it gave us many many great fights. It was hilarious and so fun. People would go straight for the ANet guy that was the bait lol! It got even more hilarious when SMC got to T3 with the ANET logo on it.
The ANET logo is a really nice bait in WvW.
