I need to know what the exact purpose of this system is.

Looks like some sort of adjustment for an automatic shifting system, but that's just a guess

The owner posted 2 videos on YouTube of it.

If it had a 3 speed cottered crankset from a cheap MTB, then it would have 30 speeds.

I don't even know why you would need that many speeds.

Sometimes, more = more

On that note, a guy in our group has an interesting novelty...

It's a Cannondale Comfort 800. This bike came with an SRAM Dual Drive 24-speed system, which is a 3-speed internal hub with an 8-speed cassette stuck to the end of it. A previous owner decided to up the ante and install a triple front crank and front derailleur for a total of 72 speeds. Neat conversation piece if nothing else...
