Seems very simple, working more with people than with problems gets you more social capital; people gonna remember someone helping them with something relatively trivial directly more than "they saw a bunch of code commited regularly". Probably anyone working long enough saw a case of someone being promoted over "better" technically candidates, just because he happened to be always there when important things happened.
