You can use a Select-SQL as a subquery for another Select-SQL, but a REPLACE or DELETE commands, not being SQL, can't use subqueries, except you use it inside a function called as part of the REPLACE/DELETE expression condition (but it can complicate things too much).
Sometimes it's better to have more readability, even if this implies the use of more than 1 line of code.
