I think a big part of it is something the article touches on: Jeff is an extrovert, Sanjay is an introvert. Jeff is the much more visible of the two; the one who people are more likely to have heard speak personally or to have dealt with. It sounds like this is how they both prefer it, but it definitely means that Sanjay's contributions get passed over in the common discourse. I was also glad to see the article avoid that trap.
