Subler - What is "Fix Audio Fallbacks"?

[llee]

When I remove commercials from recorded TV before encoding, I often encounter a 2 second audio lag after the cut. I tried Subler's Fix Audio Fallbacks just in case that was what it was for. It didn't to what I wanted. What does it do?

It is just a hint for aTV, nothing to do with content editing:
