Well, not true 2 phase, but if you look at the primary, it looks like only 2 of the 3 phases are actually connected, with the third connection being common to both transformers, and connected to the grounded leg. I'm assuming it is a grounded leg, since it is separated from the other 3, marked differently (note the yellow mark on the crossarm), and unfused.
Now if the primaries were tapped from all three of the ungrounded legs, ignoring the grounded leg, I would say it was 3 phase, but right now, it looks more like pseudo 3 phase derived from a single phase primary.
