This is completely incorrect, and the solution is way more discoverable than needing to know obscure things like Win+E. Click the thumbnail that appears in the bottom right, then click the marker icon.
> For example, "open two file browsers, navigate to $home in one and $downloads in the other, move and rename a few files between them" is a 10 second task on Windows (Win+E x2, quick clicks on the explorer links, easy to scroll around, move files, drag, rename, anything you want).
Similarly, if you know the platform-specific shortcuts, this is less than 10 seconds on macOS. Click finder in dock, hit Command-N twice for new windows, drag each window to one of the L/R edges of the screen to tile, click downloads in the sidebar on one, click the home icon/username in the sidebar on the other.
