I think this is because the buses, even with their overhead wire electric apparatus folded down, are still too large to fit in the lower clearance lanes on the Terminal B arrivals level roadway. If you look, the lanes they're blocked from (on the inside of the bend) have slightly lower clearance than the lanes nearer the curb.
I do agree though. It's the most frustrating trip. It's just slightly better than the alternative if you're going to Cambridge, but every second you're on the bus, waiting for it to switch its power source or watching it go 15mph in the tunnels, you're thinking 'how could they build an entirely new system and make it this bad?' Ah, Boston...
