If you want to go by what realistically makes sense, then \'\'none\'\' of it should realistically make sense since it shouldn\'t be possible for their spines, pelvises, etc. to accommodate both bipedal and quadrupedal movement with equal efficiency, since efficient bipedal movement requires a substantially different skeletal configuration than quadrupedal movement (which is why humans slow to a crawl when on all fours, and quadrupedal animals are much less graceful when reared up on their hind legs).

If, from there, you \'\'really\'\' want to keep overthinking it, you could allow that these animals have some bizarre alien \"gear shift\" mechanism in their skeletons that allows switching to \"4-wheel drive\" on the fly whenever they want. But that would introduce enough complicating factors that you could no longer really guarantee that the four-legged movement would actually be faster in practice.

So, I would just go by what\'s shown in the movie.
