I don't like it, and would prefer the tube being too close to starter, than too close to the manifold.
That being said, under normal operation it's unlikely to cause any issues:
1) The manifold outer shell has an "internal" air gap with the actual manifold.
2) The tube in question carries oil, so oil will cool any "excess" heat.

The reason I don't like it: oil coking after you shut the car off.
I don't know how big of a deal extra 2-3 mils of air gap are, but every little bit helps.
Also, using a heat-resistant blanket for starter is probably a good idea.
Shrug.
