Is there a reason why Let's Go Pikachu & Eevee are being counted as separate games?

The upside is that it'll be interesting the see the split between the two physical versions in the meantime, and then at the end of January we'll probably create a unified version and shift the total over to that, deleting the separate versions. Until then you'll just have to manually combine them when comparing to previous Pokemon games xD
