I just re-read the "duties of the commander" section in our operating manual (EASA approved commercial operator). It does not mention anything like that and I have never heard about it either nor have I ever seen flight crews cross-checking each other's licenses.
Anyway, the supervision status of a crewmember can not be found in the license. The only way I could possibly find out about my colleagues status is to call the operations manager or the training manager.
