Cross channel WDS ?!

Strange phenomena: 2 machines, both running hostap driver in Master
mode with autom_ap_wds=1 and other_ap_policy=1. Same ESSID, but
DIFFERENT channels. (one on 1 one on 11, but works with ANY 2 channels)
They establish WORKING WDS links to one another!
When the channels differ the WDS links are only ever at 2Mb (11Mb when
Also SNR drops in proportion to the separation between the two channels.
I've tried this with various prism2 based cards and they all do this.
Shouldn't this NOT happen? Not that its completely a bad thing, I have
imagined some interesting uses for this (full duplex with a single card
anyone?) This means that the driver is processing packets that it
probably shouldn't have seen in the first place though, doesn't it?
