We have the behavior that the prior hosts do not send any subsequent IGMP 
reports, and even the UML to send the report the latest stops after the second 
time. This makes it impossible to detect if the hosts still want to be members 
of the group or not. Maybe I can show this to you or the professor, if possible.

"hosts can detect prior reports for the same group and cancel
their own next scheduled IGMP report generation."

So it seems to be the correct behavior.
