That's actually not true - Squish / Stretch are all part of 2D Rig Animation. Spine2D has soft meshes and physics. Doing hair / breast jiggle physics is really easy although I doubt he's using physics, but I do think he keyframes the squish and nipple motion.The sprite sheets are the giveaway that he did hand-animate them. Those frames aren’t just the same parts rotated — they show redrawn motion, squish/stretch
The redrawn poses are probably just separate rigs / poses. Each pose has a unique sprite sheet of frames. He's got the Side walk animation (which he flips) then the standard "idle". There's zero transition from one to the other. It's a binary swap.and pose changes you can’t get from a rig alone.
Even if there was transition frames - this is done a lot in 2D rigged software through layer swaps (swapping a closed hand with a open hand on a keyframe to show a different angle). Also Spine2D allows you to export your animation as a rendered Sprite sheet and you can even clamp your physics to force symmetry for the outputted animation sprite sheet so that your first and last frame "match" and you don't get weird physics artifacts.

He may do hand edits afterwards, or he may do everything in Spine.. or he may hand animate everything - all are valid workflows and I would believe any of them but without him saying we can't know. I always assumed he does hand animations like Inusen until the space level where he clearly used a sprite atlas in-engine vs outputting a pre-animated sprite sheet.
