four of his paths start at second level nodes.

It's always good to generalize.
My concern is how one shows there are countably many paths through the infinite nodes. I can't move to the second path though infinity until I've completed the first, that is unless an algorith is proposed that lets me idenify which infinite paths I've taken without completely taking them. I might identify a path by its representation as a rational number. Unfortunately that leaves out the irrational numbers.
