PTP 550 load balancing with single source/destination

What a job!
I understand that each flow that meets the three conditions (TCP / UDP + src IP addr + dst IP addr) will go through the same link, is that correct?
Then I have one question: If all the traffic passing through the two-links-configured PTP 550 has the same source IP address and the same destination IP address (e.g. one UDP video transmission), will the load balancing algorithm cause all traffic to go through the same link (A or B)? If yes, consequently the other link will be empty.
