Fred,
BYE will terminate the call leg identified by the tag in the To or From
header (depending on who is terminated the call). In your example, the 200
OKs from X and Y will have different tag values added to the To header. When
C issues the BYE, it would include the tag for Y in the To header. Only the
call leg to Y will be terminated.
