[SR-Users] max_contacts does not work as expected

I have a Kamailio server that has:

modparam("registrar", "max_contacts", 2)

But recently I noticed some users have more than two records in the
location table. For example one of the users has three different records
with nearly the same information. The records are as follows. Is this
behavior normal? (I am using Kamailio 4XX).
