Assuming that a motor is wired up to L1,L2,L3 (in that order) and it is moving forward. I understand that swapping two legs will cause the motor to go in reverse. For example: (L1,L3,L2), (L2,L1,L3), (L3,L2,L1). But what effect would this configuration likely produce? (L3,L2,L1), (L3,L1,L2), (L2,L3,L1).

Just count the number of 2 wire reversals. Odd number, it runs backwards. Even number, it's turning the same way.

Eh? Odd number? Even number?
Are you saying that if i have "one" two wire reversal it operates in reverse, and "two" two wire reversals will cause the motor to operate forward again?

The numbers 1,3,5,7,9 are odd numbers. The numbers 2,4,6,8 are even numbers.

And you adding clarification to your question after I answered really makes me look sarcastic, but your premise in post #3 is correct. Every time you swap 2 wires, the motor reverses. Two reverses is back where it was in the first place.
