I had a mobile mechanic look under the hood to fix the tensioner recently.
He gave the engine a push with his hand and seemed to think the mounts are ok.

Now im even more confused

This is NOT a good test, unless this man is extraordinarily strong.
When worn, the mounts sag, the engine's oil pan may hit the subframe.
The mounts are more complex and much softer, so they will not last as long as the car in many cases.
