When the biceps is acting concentrically, the triceps is actually contracting eccentrically in order to control the movement. If the antagonist were to 'shut down' then their would be a complete lack of movement control...further the joint over which the muscles cross would be subject to shearing forces (which they don't like). If you go to my blog site "FunctionalAnatomyBLOG" and search 'reciprocal inhibition' I provide all of the necessary literature.
I'm sorry to say that the technique used in PIR is "Autogenic inhibition" which the contraction of muscle A causes subsequent relaxation of muscle A which is the same muscle. It's not Reciprocal inhibition although it is also used as one of the techniques to relax antagonist muscle.
I am not sure what your saying about useless flexibility in the yoga context. It seems you mean that the gains in flexibility after one hour of yoga are useless because your suddenly more flexible after the hour but it doesn't last. The fact that it doesn't last very long doesn't mean that new barriers were not reached and thus new CNS thresholds. All of which would lead to lasting results when done with consistency (just like PNF/PIR) done consistently. What say you? I like your videos and may take your seminars when out of school for PT. I'm going to have to check out the literature on the RI you provide because (as far as I know) my school still thinks it legit.

it amazes me that with all of the research disproving reciprocal inhibition, it is still being taught today.

Is it not true that if you contract the biceps brachi the antagonist triceps brachi usually neuraly drives down most of the time

"The concept of reciprocal inhibition has been disproven for many years now, I think it was back in the 70s"
