If not friction, what about suction? I've noticed that with a freshly, properly sharpened iron, after getting to the point of a taking a full width shaving, pushing the plane across, and then lifting the plane from the stock, requires noticeably more effort. I've also noticed the same thing lifting a board off the outfeed table of the jointer when there are fresh cutters installed. (The outfeed table is 34" or so long -- this occurs with a piece of stock less than that length. Of course you can push the board past the end of the outfeed table and it's easier to lift away.)

I have two planes with corrugated soles -- #4 and #6. Using the #4 with corrugated soles, this has never occured.
