The problem is that the handbook doesn't establish which of the two merged sections it belongs to. Of course, an answer would be "the both of them, because they were merged." However, that's not true because only their remains were physically juxtaposed, not the realities themselves

"Earth-61610" seems to be more of an alias, and not an actual reality number. I don't know if the accuracy of this designation affects another stated fact, that the two realities that made the Kingdom of Manhattan aren't Earth-616 and Earth-1610 but similar realities. I know this speculation of my part, but maybe this is consequence of Earth-616 and Earth-1610 being essentially in the same space when Doom salvaged them to create this domain? You know, there were only both of them in the entire Multiverse and then the final Incursion happened, the two of them might have become one.

That could be an explanation. However, it appears that the Ultimate and Marvel Universe regions of the Kingdom were separate, like the sub-domains of the City, for example, up until Stark did that thing with the dimensional rift that was never brought up again.
