@Lift Blog I do see what you are saying with the turning limiting capacity and having two turns and splitting to help with that, but it wouldn't be a doubling effect would it? They still have to merge back and take a set space on the straightaway. I am sure you are looking for any examples now or where this has been seen before.
On the other hand to add to the speculation, I do think the idea of having a separate slowed or stopped area for the ECV and wheelchair or other loading could work especially with how short that second turnaround is. Apologize for the crude drawing:

So if I understand correctly everything after the red line I drew is off of the cable. So in usual loading the blue track is slowed down unload and then load. Now possibly (total speculation) they could have one or some number of stopped and staged gondolas on the orange ECV or stopped loading track. And once they load the gondola on the orange track or have someone who needs to unload on the orange track, the operator would push a button or if the systems are good enough and tracking specific gondolas (I have no clue about the control sophistication) it would be done automatically. This would then take an empty gondola or the gondola needed to be unloaded off of the blue track onto the orange leaving a gap then a staged gondola that was already on the orange track or one that was just loaded up would then be fed into the opened space on the blue track as it came around. So the total number of gondolas and the spacing would be constant on the line. This could work even if unloading someone on the orange spur track and an empty already staged gondola from the orange track was put into the blue track to fill its place as the empty gondola would then go through load and be loaded so no efficiency is lost. Interesting design at least in theory.
