I think Stefan is saying there's a difference between

(should not cause signalling, should not cause track1 to be sent)

(causes track1 to be sent without a stream)
(causes nothing to happen - stream1 is empty)
(should this cause signalling that track1 is now a member of stream1?)

All sequences of *.Add* shoud have a deterministic result, even though
the result of nonsensical sequences doesn't have to look very sensible :-)
