Section 2.2 says:

   Varying this setting allows IGMPv2 routers to tune the "leave
   latency" (the time between the moment the last host leaves a group
   and when the routing protocol is notified that there are no more
   members), as discussed in section 7.8.  It also allows tuning of the
   burstiness of IGMP traffic on a subnet, as discussed in section 7.3

     Router Present Timeout] and starting it.
   - "reset timer", resetting the timer to its maximum value [Version 1
     Router Present Timeout] and restarting it.

Notes:

Resetting timer is obviously different than setting timer.
--VERIFIER NOTES--
I am rejecting this Erratum mainly because RFC 2236 has been obsoleted by RFC 3376, but also because I don't agree that the change is needed. The original text covers the two operations adequately.
