If you consider the sum of the physically separate currents on the
inside and outside of the shield to be the current "through the shield",
that's correct. And it's equal to the current on the outside of the shield.

Yes, I was calling the sum of the currents on the inside and outside
of the shield, the current through the shield. Sorry, if that is a no no.
