This is an uneducated question, but shouldn't there be three tubes bracing
the upper engine mount ( the one by the water pump) ? Or is it just not
visible in the photo?

I think you are referring to Mike's motor mount.
To be rigorous in engineering design terms the answer is yes.
A lot depends on the actual stiffness of the rubber bushings
whether enough bending stress is induced into this tube to crack
it over time back near the firewall joint.
