INTERCEPT In SQL Server 2005

I was writing a query and managed to mistype INTERSECT, I typed INTERCEPT and to my surprise the query ran, it returned 2 result set just as if INTERCEPT wasn't there at all
Try it yourself

CREATE TABLE testnulls (ID INT)
INSERT INTO testnulls VALUES (1)
INSERT INTO testnulls VALUES (2)
INSERT INTO testnulls VALUES (null)

CREATE TABLE testjoin (ID INT)
INSERT INTO testjoin VALUES (1)
INSERT INTO testjoin VALUES (3)


SELECT * FROM #testjoin
INTERSECT
SELECT * FROM #testnulls


SELECT * FROM #testjoin
INTERCEPT
SELECT * FROM #testnulls


Feature, Bug?

Okay, it actually doesn't matter what you type between the two statements

SELECT * FROM #testjoin
sdsdsdsdsd
SELECT * FROM #testnulls

That runs just as if you executed the query without sdsdsdsdsd

WAKE UP!!! That acts as an alias, now where is my caffeine.
