re: Sequence Number reset after logon

This question may be simpler than I made it out to be.
Yes, I believe A should send 8 as the NewSeqNum because B asked for 1-7. But the next message A should normally be sending is 9. The only exception is if B asks for a ResendRequest of 8, and then 8 becomes a SeqReset-Gap Fill because Logons are never resent.
If A were to send, say, a Heartbeat or an application message with sequence number 8 after already using it for a Logon, then I think A is doing something wrong.
