Not necessarily. You appear to be doing IP+port based matching. If requests always come from the same source IP address and port, then it would match only one. Turning on sip debug using "sip set debug on" and verbosity using "core set debug 9" would give you more information about each packet (including where it is from) and what was actually matched based on it.
