The long and short of it is that the EU, in determining the gatekeepers, looked at the monthly active users for each store separately on the premise that each OS (i.e., iOS, iPadOS, macOS, tvOS, watchOS) is separate from each other with its own constraints, functionality, and purpose. The EU then realized that the only App Store that meets the monthly active user threshold is the iOS App Store (and maybe iPadOS, I am not 100% sure as I write this, the preliminary findings were a while back), which wasn’t desirable for the EU as they want to regulate as much as possible. Hence, the EU basically said: “fuck it, we’ll treat them all as one; the DMA is written vague enough that we can get away with this.” Apple is now appealing this finding and echoed the EU’s original stance that these are to be considered separate, with each their own monthly active user threshold to meet.
