He does spin them physically at some point- it's in one of his idle animations, iirc.

As for when Spinning Blades itself is active? I haven't seen any official explanations or anything like that- best I could do was watch his clip from A New Dawn at quarter-speed. Still not a lot to go on, but it looks like he gives them a little starting momentum and then just maintains it. You can't tell on his in-game animations, obviously, but I think that's what they were going for.
