I think the comment in SDWAEC1 is quite clear: Extended control PSW at time of error(abend). When the error was a program interrupt within transactional execution, this is the PSW at the time of the program interrupt within the transaction.
It means what it says. When you mention an RB, it is important to identify to which RB you refer.
