I have a little theory on these guys. I'm probably way off base but here's what I think... Suppose CA-06 is a tank and CA-07 is a jet. Both are involved in some capacity with the C3/A3 storyline. Both have secret combiner ports that can be linked to C3 and A3. In reality, CA-06 is Brawl for the Combaticons and CA-07 is Fireflight for the Aerialbots but we are not told that .
