These are the most trivial examples.  The second one results in a syntax error.  Which implies that:
1) There can only be one recursive CTE at the same level?
2) It must be the FIRST CTE?

There is only one WITH keyword as well, that doesn't change the fact there can be multiple attached queries to it.

The documentation explains clearly the implications on adding the keyword RECURSIVE after the keyword WITH.
