we do have proof of it not being the garden but the outside world. first off, Toad can be seen in the garden yet he doesn't go trough the window to get there faster. also if it would have ben the garden the yoshi easter egg would also SOMETIMES be found in it. however since the "window exit" is way to close to toad, it's not a safe and reliable way to escape.
