Thanks for testing! You're right, looks like in the current implementation in case of backwards scan there is one unnecessary extra step forward. It seems this mistake was made, since I was concentrating only on the backward scans with a cursor, and used not exactly correct approach to wrap up after a scan was finished. Give me a moment, I'll tighten it up.
