I assume the voicing you're showing is that one chord HH bangs out over and over again in the first few minutes? (Although to my ears he's not always playing the exact thing, he seems to vary it a little.) Truthfully, I'd describe it as a "cluster" rather than a "chord".
This tune and the way they're playing it is not standard harmony (I'm listening to it right now) but rather a modal based scheme based on the notes of the melody. So it's probably inaccurate to describe that big cluster HH plays as any particular chord name plus extensions. The "harmony" is static so the usual aspects of functional harmony like one chord resolving to the next, or creating tension to lead into a cadence, are simply not relevant to the way they're playing.
If I had to guess, I would guess Herbie fooled around with the melody and with different ways of playing piano on this tune, and ended up deciding to use a big cluster banged repeatedly, then he built that cluster off the notes of the melody. In other words, if my hypothesis is correct, he didn't consider it a Bb7/9 #11 13 or whatever at all, he built the cluster according to how it SOUNDED.
I am willing to bet that Herbie certainly didn't look at a table of overtones when deciding what cluster to play.
