I think Steve is saying that there are three bus bars in the box: one ground (for everything), one neutral for the shore power, and one neutral for the inverter.
It's not too surprising since some inverters do not actually have their neutral output at the same potential as (chassis) ground, but are actually producing a pair of out-of-phase 60V AC waves at the neutral and hot outputs. This approach means that the internal voltage rails can be half what they would otherwise be. (Others use a similar approach but have the output floating and electrically isolated from the DC input, and in those the neutral output could be tied to ground.
Thank you! I couldn't have explained it better myself!
