That's a wholly uncharitable reading of what he's saying. A way more good faith interpretation would be the very simple equation of "working with just computer - more thing oriented, working with computer + partner - more people oriented". This may be wrong(I don't have any evidence to back it up, and neither did Damore), but it is wholly different from the sinister undertones you are seeing. (In fact, taking your "mentorship" interpretation, it is entirely possible that the women would be the one doing the mentoring, if their skill at engineering was hampered by a disinterest towards purely thing-oriented pursuits).
