Okay...
I'm assuming the question is contained in the phrase:
"I’m dying to know how he got all that cash into it when you are only supposed to be able to add $6000.00/year."
The answer given in the article was that it is likely he invested stock at a very low price and it appreciated.
It's not uncommon--I've done it myself (with a Roth), except the company founder's stock I invested never appreciated. That's part of the risk.
