Yes, you're right they are in reality only attached to the frame at 2 points (I was just trying to differentiate from the ones in the 1st photo in your link)
What I did notice was that - whether intentionally designed to do so or not - because they are bolted to those plates, the bars can move a small amount, so there is a bit of "give" and the force is not directly transferred to the frame or engine bolts, not straight away at least. Another bonus is that it is very easy to remove the bars as you can simply remove them from the plates so you can leave the engine bolts in situ.
