Richard, I think you would be surprised if you measured the RF current
through the short at the shorted end. It will be the in-phase sum of
the forward current and reflected current and is quite high. I once
melted the insulation at the end of a shorted 1/4WL piece of RG8X.
The heat came from high I^2*R losses at the short.

The SWR inside a perfect stub is infinite.
