They're not really ok though. You have to flip both horizontally AND vertically to get the correct results:
1. Flip the fretboard left to right so the open string is on the left
2. Play the open strings by clicking their names, hear the correct pitches
3. Play fret 1 on the low E string, you hear an F two octaves up (ie fret 1 on the high E string). Continue with fret 1 on the other strings - on the A string, you hear a C, as if you were playing fret 1 on the B string.
So it's only flipping the open strings, and not inverting the fretboard. I guess the idea is that you can have righty, lefty, and lefty-strung-righty, but the labels are wrong so I think this is just a mistake.
But, click both flip buttons and you'll end up where you want to be.
