Einstein’s elevator explains why acceleration can mimic gravity. It doesn’t, by itself, explain why a stationary cube would emerge with a large sideways velocity. That conclusion depends on additional assumptions about how moving portals transfer momentum.

Yeah it does explain it if you use your brain for like half a second. Is the orange portal moving down to the cube or is the cube moving up towards the orange portal? We have the reference frame of the cube so it looks like the portal is approaching the cube.
