On: NASA lays out how SpaceX will refuel Starships in low-Earth orbit

you would but you need to stop the spin and then dock the two together.

That would send fluids to the back of the tanks.

At this stage it might be easier to build fueling station in the orbit with actual transfer pumps.

I'd definitely prefer to decouple the carrying fuel to the orbital depot and the refueling at the said depot, when it already does have the fuel amount needed.

As for spinning two Starships of significantly different mass... that should be interesting to see. Doable, yes :) but interesting nevertheless.

Spin after docking, of course.

Pushing the liquids is not the hard part. Settling the liquids in 0g is the hard part.
