Law of conservation of matter, Orochimaru's new body rejects him so both bodies must be present. Yet Sasuke saw several people in Orochimaru's "dimension" if he had several bodies worth of matter he would be too dense to move.

To be perfectly honest, I am not exactly sure how White Snake works on a manga level, let alone a science level. This could simply be one of those whole mass-shunt ideas, a la Optimus Prime's trailer from transformers. If Orochimaru has his own personal dimension, he could then shunt the corpses into that dimension, reducing his White Snake's density enough to stay mobile. To be fair though, the law of conservation of matter only applies in thermodynamically closed systems; since the technique literally involves a microdimensional portal being accessed, it is thus perhaps one of the most thermodynamically open systems ever.
