Technically as soon as the word "Reject" is spoken the captain becomes PF, the Boeing SOP is that he or she has their hand on the thrust levers from the call of "thrust set" to "V1" even if the F/O is PF until the RTO begins (as I'm convinced you know), so it is the PF who decides how much braking/reverse to use.
As for the rest of the discussion, none of us are immune to errors, as rrramjet said it can happen to any one, and whilst experience levels may be an issue it's not always the case. We used to do the before take-off check list as soon as we got cabin secure, then someone decided they wanted us to do it at the holding point, because they said we shouldn't have the radar on so early during the taxi out. So shortly afterwards at some Sh*te hole in darkest Africa we were taxying out with all the normal distractions of mad bush pilots, mad Russian helicopters, pissing rain and incomprehensible ATC and only realised as we lined up that we hadn't done the before take-off checks (although the aircraft was at least correctly configured). that day on the flight deck I had twelve years experience on the 73 and the F/O had ten, and 29,000 hours logged between us, but we still got it wrong.
As for some of the other issues being raised, the Boeing on board performance tool doesn't require a 90 degree turn to line up, like we used to do, an allowance is built in depending if the runway entrance point is at 90 or 30 degrees or a 180 degree turn after a back track. And using the Boeing OPT for a max weight 800 at sea level, standard pressure and ISA plus 15 then calculations using optimum flap settings will give flap 1 for take-off for runways as short as 2000m if there are no obstacles, so as was suggested, the second video clip was almost certainly an early rotation or the aircraft wildly out of trim rather than an incorrect flap setting.
As was said earlier, there but for the grace of God....
