It took me some time to figure out why, but you are right, the ambiguous
transitions occur only while counting up. What you could do though would be to
count +1 while going from state3 to state2_ambiguous, and correct "phantom
transition" by substacting 2 if the next level read was L1. This way the
up-counting would be regular "by 1" in most cases.
What does your state machine do when you get a L1 to L2 transition, that can
occur when going from L1 to L3 CW (same thing for the L2 to L1 when going from
L2 to L0 CW)?
