I don't see how that play was Pillar's fault either. One of the first rules you learn in baseball is to defer to the centre fielder the second he calls for the ball. (It frustrates me to see Bautista run over and completely ignore those calls)
The reason it was Pillar's responsibility comes from the same reason that an infielder should defer to an outfielder. It's easier to make a play coming in on a ball than back pedaling because not having to turn around gives you a better awareness of the situation. For Tulo to know where the outfielders are he has to turn around, for Pillar to know where the infielders are, he has to momentarily look forward. It's Pillar's responsibility to have a better awareness of where everyone is in relation to the ball.
Because, as I'm sure we'd all agree, we'd rather that Pillar have known where Tulo is and backed off even if it meant the ball dropping.
