(you know this, but for the benefit of everyone else...)

They use the SC's that are legal under Whitlow for domestic, then use the ones that have timed out under the most basic of rest rules to staff international where they interpret that there "are no rest rules."

The FAA somehow did interpret Whitlow as a domestic only rule. So while you would not be legal for a flight to Seattle, you could be just fine for a double red eye to Manaus and back, or a deadhead to NYC then be part of an unaugmented crew to Europe.
