I think Erik hit the nail on the head with DELETED() when more than one table involved.
Another note: I used to have problems when my local alias's were single letter and matched the old A-J alias names for the first 10 areas. I don't know if this is still a problem or not, but I just got to the point where I didn't (couldn't) trust it, and used SQL local alias of 2 or more letters.
