i'll tell the contractor when I talk to him later and ask him whats up.

I love it when the customer has to tell the handyman how to do things.

3/8" over plank subfloor? Well, that's wrong too.

Read the direction for your vinyl flooring to see how to handle the seams of the underlayment, after they're properly fastened of course.

In the end 3/8" over planks might be good enough in this case if: The planks are in excellent condition. Generally you'd want to use minimum 1/2" over planks if they are perfectly flat.

I'm pretty sure the instruction are more detailed than that. Specifically which floor will you be installing?
