That works.  I would have written:

REM Wed 21 +2 AT 18:30 DURATION 2:30 SATISFY [$Tm == 1 || ($Tm != 12 && !($Tm %2))] MSG Special meeting %b %3

because it's more efficient.  (Try both with the -dx flag to see
how often Remind evaluates the SATISFY expression.)

Note that you need a recent version of Remind for $Tm, which is equivalent
to monnum(trigdate())
