Re-read the article. The fourth day thing is the ex-divy date. Right after that is Payment Date...which doesn't say how long it is before the company pays you...just says it's the day that the company pays you.
Let me also share an observation with you. I have found that if the Pay date closely follows the ex-divy date, say like 3 or 4 days, you will likely see a big down-draft in the stock on ex-divy day. Everybody takes the money and runs. However, if the Pay date is more like 3 or 4 weeks after the ex-divy date, the down-draft effect is usually vastly reduced.
(Note that NM ex-divy date is 6/16 and Pay date is 7/2.)
