This dinosaur would have similar issues, I would think.

There's been a similar discussion and debate regarding the sauropod ("Brontosaur"-type) dinosaurs for years, having to do with the high level of blood pressure that would be required for the blood to reach the animal's brain when it (if it) actually did rear up on its hind legs to eat from the tops of trees. Dino expert Bob Bakker argues it could have been possible as these creatures had very tiny brains and so wouldn't have needed much blood going to their brain. The problem with the high amount of blood pressure is that once the animal came back down again the enormous blood pressure would nearly blow its head off. In other words, he believes it was beneficial for these particular dinos to have small brains. He calls them "Darwinian morons".
