It that so?

I thought it means that the current density over the thickness of the foil
is almost uniform with result that AC and DC resistance are almost equal.
But even with the thin foil that resistance will be so much smaller than the
resistance via the real earth that I expect  almost all capacitive current
from the coil is captured by the foil.
Am I wrong?
