(To clarify, in case you can't see the original, I wrote that as two sets, separated by a blank line, one 1,2,3 and then another 1,2,3 again.)

...yes, see, like that. That seems broken. That is not what I wrote.

My biggest objection is actually to the renumbering — I numbered my bullets precisely so that I could refer to them by number later. So maybe there's a way to say, "hey, I'm about to combine two lists in a way that causes a numbered list to be renumbered" and just not do that?
