1- If two files completely cancel out when polarity inverted and summed, we can assume they are the exactly the same, agreed?

Yes
2- If you add your two audio examples together, the original and the polarity inverted, they will cancel 100%, right?

yes
3- If so, how then can they be different in any way?

they can't, they are the same. but that's not the case here. if you split a signal and send one into a Pulveriser and another one with reversed polarity into another Pulverser they won't cancel. so both versions are not affected in the same way by the Pulveriser.
IF they ARE the same, as you say above, then why do you hear a difference? Could be your speakers aren't symmetrical?
Is what you describe above not different from what you first described? In your original audio example, you have taken the output of one Pulveriser and inverted the polarity, then switched it back (and repeated), right?
BTW, two Pulverisers with 50% "dirt" cancel almost 100% leaving about -90 dBFS residual level. Pretty damn close in my book - is this different than what you described?
[edit for clarity: split the signal, inverted polarity going INTO the second Pulveriser, summed both Pulverisers to mono, near perfect cancellation.]
