Saying "last to be caught by robot arm" isn't really accurate. I heard Elon say that the cargo berthing hatch (50" square) would still be used to load/unload cargo larger than will not fit through the docking port (31" round). As far as I know, to do that would still require the robotic arm to position the cargo hatch for berthing.
