SQL is big on providing ways to give aliases/names to things.  It just
boils down to readability or, more often, conventions, as to which ones to
use.  The CTE column names clause doesn’t get used much that I have seen.
You have to write a full query inside the CTE anyway so column aliases are
more conventional.
