does this script work in a query window? i could be wrong but i think you might have to put an "as Size" after the cast statement.
No, the two select statements are in a union. The first select statement will control the column names. If this was not the behavior then it would allow for the same column to have two different names in the same query.
Here is proof:
select 1 as MyColName union all
select 2 as SomeOther
