I’ve just seen this so I guess take what you want from it. To me this makes more sense

If that is the case, then that will make more sense - still not 100% sense though.
They would be able to see that you have reservations to be on-site, so will likely turn up, so will be more likely to use it.
However, that means that it wouldn't be an app issue, or a website issue, but a choice that Disney is making to move international guests on-site (which makes business sense).
However, confusion is going to happen, unless US blogs/websites would start phrasing instructions on how to use the system like below.
=====
If you are staying on-site, LLMP/LLSP reservations open up 7 days before arrival, and you can booked for up to 14-days.
If you are not staying on-site, LLMP/LLSP reservations will open up 3 days before you plan to use your ticket for entry, and can booked once you have entered the US.
Three parks (MK, Epcot, DHS) have tiers...
=====
Otherwise, people are going to read (like we all did yesterday) about booking 3 days out, and then they will try and not be able to.
If this is the case, then they should have just announced it like that yesterday, instead of causing more confusion.
