You are absolutely correct! The ex-date they show in the example is for a cash divi....I think! I think for the stock dividend the ex-date is after the pay date. In this case they are paying out the divi after the close on December 15th a Friday, to owners of record December 1! It will be trading "ex dividend" on Monday at the open December 18th.
Now this is totally oposite what you have been saying and what I was told today by Scottrade, so..........I am searching for further information and clarification! LOL!
