I just tested this too, because I thought that one had to do

   [ "$CTL" != "yes" ] || takeaction

rather than

   [ "$CTL" = "yes" ] && takeaction

when -e was set in order to avoid immediate exit on the failure
of the "$CTL"="yes" test.  Experiments prove that neither of
these causes immediate exit, even though the second one does
have a nonzero status when "$CTL" != "yes".
