I swear I remember reading somewhere about an alternate, shorter JOIN syntax in cases where the column being joined has the same name in both tables. But I can't seem to find a reference to it by Googling. Am I misremembering?

It was something like this:
SELECT T1.ColID
FROM T1
INNER JOIN T2 ON ColID

I've never seen that in T-SQL. MySQL maybe?

I think it was in one of my Louis Davidson books, it was almost definitely T-SQL. But I'll have to go try to dig it up.

T-SQL has no join constructs like that.

Oracle (iirc) has a NATURAL JOIN which joins on the foreign key columns, but SQL Server doesn't have that
