The function is not only a check--it also has an effect on execution 
behaviour for non-CANCEL / non-ACK requests.

Consider:

http://www.opensips.org/html/docs/modules/1.5.x/tm.html#id272150

"[I]f the request belongs to a transaction (it's a retransmision), the 
function will do a standard processing of the retransmission and ***will 
break/stop the script***. The function return false if the request is 
not a retransmission."
