Presumably, yes. I know the ETD machines pick up GSR, so it's a logical assumption for me to think that the woebegone puffer machines would pick it up, too. We don't have a puffer in HSV though, and since TSA is pulling out of the puffer market for a variety of reasons, I doubt I'll ever get to play with one.
As for the second one... meh... difficult question to answer when it comes to dancing on the SSI line. Basically, just pretend like you had the SSSS marks on the boarding pass, and go with it from there.
