Right, under reserves it looks for all intents and purposes like if a DS unit mishaps into Ongoing reserves it now has to walk on from the owning players table edge. That also includes Mawloc burrowing and the swooping Hawks bugging out and coming back in.
However; under the psychic powers there's a suggestion that maybe, just maybe that wasn't RAI, as a unit conjured deep strikes within x" of the psyker; but if it goes into ongoing reserves (that's the key, it specifically mentions 'ongoing' reserves) it can then DS anywhere on the table when it arrives.
Now is that just poor wording under the ongoing reserves rules so that once again RAW and RAI don't match up, or is it actually specific to conjured units?
