Not the OP, but I never know where a specific application will show up. Sometimes Chrome is on the left and my IDE is on the top right, sometimes it's the opposite. If it relates to the window location, I can't tell. Always mostly the same set of five or six applications, too.

Oh, you all mean when expose or whatever it's called shrinks the windows down and spreads them all out? Yeah, I've never found it a useful way to switch apps if I have more than a couple open. Visually searching for the window I want like that isn't fast for me, and if the windows get too small it's not helpful.

Original Expose ca 2003 minimised windows from their live positions on the regular desktop to thumbnails in a quick and smooth animation and would leave minimised thumbnails at different sizes resembling their relative live sizes and aspect ratio.
