I'm guessing the top tube to seat tube joint will go first, because it's the corner of the unbraced square with thin walled tubing on both sides.
Agreed. Not the optimal geometry, but strong enough for the application. Look at motorcycle frames, they typically have a square front end to accommodate an engine. This is pretty similar.
