It blocks the configured subnets:
- at ingress on one
- at egrees on destination.
I.e. a packet arriving on the WAN interface *from* one of the configured
subnets or a packet departing the WAN interface *towards* one of the
configured subnets will get dropped.
You could presumably still send a packet from the inside with a spoofed
source address, but that source address would then get rewritten by the
NAT filter...
