No.
For SQL
select id, t1 from(
select id, a as t1 from t
union all
select id, aaa as t1 from t
) k2;
The analyzer instances for select id, a as t1 from t and select id, aaa as t1 from t are different.
Such as, The analyzer instances for select id, a as t1 from t is 6177, which ancestors are[6219,6220,6221],
The analyzer instances for select id, aaa as t1 from t is 6225, which ancestors are[6247,6220,6221].

For different Analyzer scopes, the id for SelectStmt maybe the same, but the Analyzer instance always unique
