No, I don't think saving memory is a viable excuse even on consoles. The complexity of the scene with Harbinger simply doesn't seem that great -- and if they needed to make more room for Harbinger's model, they could have simplified the environment instead. Disc space isn't a viable excuse either, since if they were really running into problems they could have spread out to three discs instead of two. The only reason to do it is to save labor.
