I think they intended to continue "... without changing their aspect ratios".

I.e. an aspect ratio of Sqrt(2)is the only one where the inner screen (full) and inner screen (half) match, and they seem to have tried to make the outer screen share a nearly identical aspect ratio too. I guess it's a nice consideration for more consistency in layouts for apps targeting the device. Not sure I'm particularly excited about that myself though.

it's a neat tidbit, but not important in the slightest imo. Probably helps with smoothly transitioning between modes, but that's not been a particular pain from my foldable use.

Android devs have always had to handle different screen sizes. Not the case for iPhone devs e.g. I have a game "Ridiculous Fishing" (from 2013) which is a mess layout-wise on my iPhone because it seemingly hardcoded some pixel values and used percentages for the others. They have a fixed version for Apple Arcade.

		The first new resolution for an iPhone was 2012 which also saw the introduction of Auto Layout. The second new resolution was in 2014 which added size classes. It's entirely possible that the 2013 game was built before they actually started caring about this. This is a non-issue for almost all apps you're realistically going to encounter.
