As somebody above stated, I got to thinking about it and also think the oil would be in the pan, just the same as if the car had been, turned off, and restarted, which if have done an oil change, I would hope it had.
I had also been doing this with past oil changes, and actually did it with my last one, on the weekend.
I spoke to a friend of mine who was a senior mechanic at Chrysler Jeep, and was trained extensively and worked on these motors, and now works at Subaru.
He said the only time they do something like this is if there has been some sort of major tear down on the engine. In that case, they will also disconnect the ignition, or fuel (in diesel case) and turn the motor over until the pressure comes up to psi before firing the engine up. In this case they use an external gauge, not the "oil light" which trips off around 8 psi.
I also asked Conflicted racer this question after seeing what he recommended and finding he recommended the same practice of pouring 4-5 quarts down the filter side.
For those of you that do not know Conflictedracer, it is one of the best WK sources of mechanical and maintenance info on the web.
One thing I have found is some people (not necessarily WK CRDs) are accidentally dropping plastic, or aluminum foil slivers into the oil filter center hole when priming their filters, or "dry" side of their v blocks. This can have catastrophic consequences. If you do put oil down your filter hole, please make sure it is only oil.
