RFC 3810   Section 8.3.2.  In the Presence of MLDv1 Multicast Address
Listeners

   Note that when a router switches back to MLDv2 Multicast Address
   Compatibility Mode for a multicast address, it takes some time to
   regain source-specific state information.  Source-specific
   information will be learned during the next General Query, but
   sources that should be blocked will not be blocked until [Multicast
   Address Listening Interval] after that.

When a router switches back to MLDv2 Multicast Address Compatibility Mode
why does it wait for Multicast Address Listening Interval after regaining
source specific informations to block sources?
