Maybe a good time to point out that LAWA officially retired "Terminal 2" from its interactive map. It will slowly remove other signage and maps showing refences to "Terminal 2".
It is Terminal 3 which has two concourses - one of them being the former T2. The North side will go from T1 to T3 and then TBIT.
I imagine once AA is done with its T4 and T5 rebuild, it will similarly be rebranded as a single terminal with two concourses.
