So I don't understand, you're physically sending two different SMSs here.

Again, you're sending two SMSes according to the log.  First with 2 
recipients, and second with a single one.  This means three SMSes are sent, 
and presumably one of the recipients will get 2 of them.  All three get sent 
eventually.  What is the problem?
