Question about Building and Sending Group and Source Specific Queries ( RFC 3376, section 6.6.3.2)

HI,
In the paragraph of the section 6.6.3.2, when building a group and
source specific query, two separate query messages are sent for the
group, the first one has the "suppress router-side processing" bit
set, and the second one has the bit clear.

My question is that if the first query's S bit is set, then the
non-querier router would not lower its source timer to LMQT, and the
source timer in the querier router equals to LMQT, so when the querier
timer expires, the non-querier timer is still running, this would make
the inconsistence between the non-querier and querier.

Can someone give me some suggestion.
