He plays individual notes at 0:19.You can hear the clash at 0:22. Is the distortion/clash caused by the note hitting the next note because of the amount of delay he has on it? almost like the note in the delay is clashing with the note being played in actual time?

He's just hitting the same note on different strings...

But I'm a noob and dunno what I'm talking about

^^^ Yeah, that is caused by a slight problem in intonation/tuning. It is called beats frequency.

If the two pitches are slightly off, the wavelengths will basically 'bump' into eachother at those 'off' places.
I use this to tune my guitar actually. Once I get the low E, I do relative tuning, and just feel the vibrations of the wavelengths through the body of the guitar. Pretty nifty.

but he's playing different notes, not octaves. does the delay not have anything to do with it? it sounds almost like the delay note from before is hitting the real time note. am i wrong?

I listened to it again, and it just sounds like normal distortion to me. :/
For example, on a slightly dirty setting, play the open A string. Hold it, then (while still holding it), play the 2nd fret D string. It gets distorted.
