Someone has a good imagination!
The only thing that I can figure out is that the artist is either (a) a Film School student that used his/her imagination and creative arts skills along with their knowledge of PV to compose this vid, or (b) some sort of a physics engineer that's trying to prove out a theory on the Laws of Physics might apply to an event like PV - but a "LITTLE" more complex.
Really, it's more of a spin-off on how LJ evolved into the TJ event ... but it's more of a nightmare dream than a pipe dream on how PV might evolve!
One thing that I know for sure ... the artist is NOT trying to impress anyone with his/her knowledge of POLE VAULT SAFETY!
I would suggest to the artist only one additional feature ... fill the middle hole with water, and let the athlete dip his toes in the water (something like a bungee jumper might do over a river) before he shoots up and over the second bar. At least that way, if the double-vaulter's first attempt at re-grabbing the pole fails ... and he/she's not impaled ... they''ll get a chance at another attempt!
