You are right.

From the ipf how-to: you would be better off with something like:

block out log quick on ed0 to <iface> from <ip>/32 to any

You will be blocking the normal packet and deviating the original one 
to <iface>. Besides, I can't see the point of "to 192.168.0.2 from 
192.168.0.2".

Good luck!
