These are great explanations for why they have different team ID's.
From the sounds of it, however, they should also have different
franchise ID's. In fact, it sounds like the Baltimore A.A. team of
1890 and 1891 is more closely related to the Brooklyn A.A. team of
1890 than to the pre-1890 Baltimore A.A. teams.

As far as what the problem is with this, it's simply a matter of
team grouping. At least in my humble opinion. Not a hige deal -
just wondering really. I know things baseball-related get very
difficult to follow this far back.
