It's a great idea, and Adam is classy for a number of reasons, but having just left Quora, I only have 90 days to exercise my options, so it's not something Quora is doing right now, which is what the article seems to imply.
I think you should hit up Adam and see if he can provide you with a 9-year 9-month extension. If not, you should let Sam know so he can provide an update clarification on the article.
There is also a precedent for such type of clarification updates in YC family. YC founding partner, Jessica Livingston, provided a clarification with respects to Sabeer Bhatia of Hotmail vs. DFJ ventures based on the statements Bhatia made in an interview with her for the book "Founders at Work".
