Narrative:

I taxi my small aircraft aircraft onto runway behind landing XXX with a landing YYY airliner reported on downwind segment. While I hold my position on the runway, XXX back taxis to clear runway, and YYY reports 'base leg'. Xx 'fast taxis' back on west side of the runway as I start taxiing up east side, YYY reports turning 'final'. XXX reports 'clear of runway' as I apply takeoff power. We pass each other at north taxiway, wheels on the ground, by about 100 ft. YYY must be on a very 'short' final by now. I completed my flight without further incident and the other 2 aircraft apparently did as well. Contributing factors: the YYY crew apparently misjudged the time requirement for the XXX to clear the runway. I misjudged the type of traffic pattern YYY crew was flying. There is no parallel taxiway for the runway.
