I’d expect everything on the latter page to agree with the former but there are many discrepancies. For example, the latter says that there are 4 observations of T. albidum whereas the latter says (correctly) that there are 431 observations of T. albidum.
I do, too, now, but I must have looked at both links 25 times earlier today and except for the 4 changing to a 5 the last time I had looked they were always the same.
It probably takes some time for the observations to reindex when the species is moved from genus to subgenus (as was the case for these Trillium species).
