This change looks like it makes sense to me, but I'm curious why this is needed
in this CL? i.e. if it's required, how did similar statement to the ones added
in this CL pass before?

Prior to this change, $SUPPORTS_SXS wasn't evaluated in a condition in this
codepath's context. This is now consistent with the evaluation in
test_installer.py. It should have been updated a few revs ago when the other was
changed, but was missed since it wasn't needed at the time.
