Dona,
I am guessing they really meant to say is to keep it blank. People, I found would type null, or put a space into the box. They probably did "" because in HTML you do alt="" to tell assistive technology to ignore it. I am guessing that this connection was not made in that presentation. There is no way to mark an image as null in MS Office products. The current practice we use at work is to leave the description field empty. Assistive tech will say "image" when encountering it, but that's all. If you do a file > save as > PDF, the built in checker in Acrobat will flag it as an image with no alt, so you need to tag it as an artifact. Now if you use something like CommonLook Office to create the PDF, you can tell it to make the image an artifact when you convert it. The behavior remains the same as I mentioned above in the word doc.
