But observe the first paragraph under CAUSE. The article then bends over
backwards to do it anyway, which contradicts the first paragraph. I prefer
to trust that first paragraph that says the correct behvaiour is undefined.

Yes, but did you get expected results, because you should get them, or
was it mere chance? Compare the TOP 100 PERCENT .. ORDER BY in views that
many incorrectly relied on in SQL 2000, and then were bitten by in
SQL 2005.
