I see two different cases:

Suspend/resume: The WoL state in the kernel is probably kept across
such a cycle. If so, you would expect another suspend/resume to also
work, without needs to reconfigure it.

Boot from powered off: If the interrupt just enables the power supply,
it is possible to wake up after a shutdown. There is no state kept, so
WoL will be disabled in the kernel. So WoL should also be disabled in
the hardware.
