Thanks. As a practical matter, though, either the release you to rest, or they don't. It's hard to imagine how they can argue you've been released to a "rest" that happens to match the length if the original layover, already have assigned you the "new" trip, and be able to convince a neutral that you weren't doing a base layover on the original trip. I'd have to spend time with a CA volunteer to figure this out, but it just seems like a sketchy practice.
