I have a '51 MkVI Bentley with opposite handed wheel studs on each side. I
just went out to the garage to check, and the "Off -->" stamp points in the
direction opposite that which the wheel turns in forward travel. That is, to
remove the nuts on the left side turn them clockwise (looking at the wheel
from the outside) and the right side, counterclockwise (CCW).
This means that the right side has (ummm, visualize wheel on right front,
arrow points this way, curl fingers of right hand that way (CCW) point thumb
out, yep) right hand threads and left hand threads on the left.
I think this verifies your theory, but I wonly report the data; I will let
others interpret it.
This finger trick, by the way, is very handy, pun intended. For right hand
threads, use your right hand. Point your thumb in the direction you wish the
fastener to move, and curl your fingers around the axis. Now turn the
fastener in the direction your fingers point and it will move the way your
thumb points.
