It probably does.  Whether it does main CPU poweroff or just will keep
trying to issue a GPE asking for a shutdown, I don't know.

In that case, the CPU is still running to process EC requests (either in
BIOS or in the OS), so a thermal shutdown would be obeyed.  I don't know if
the EC would power off the box by force if a thermal event is not acted
upon.
