Result of phase flip between real-time bounce and fast bounce non-trivial

To get this result, I bounced tracks using fast bounce, and then using the identical settings using regular bounce and then using fastbounce. The initial result was a silent track. I normalized the track expecting it to be white noise, but it wasn't. 
 
The difference shows up between 0 and -48Db.
 
This is the normalized result...

I'm guessing this difference is caused by random numbers generated during the bounce. At this time, I'm attempting a second real-time bounce. Again, I'll flip the phase on the second real-time bounce from the first and bounce the two together. I should expect the same low level sound below -48Db if the difference is due to expected randomness.
 
And indeed, it does. The same sort of random differences exist on 2 real time bounces.
 
There is no question here. I just thought I'd share the result in case it amused any of you or brought about any interesting comments.

I make some videos. This one shows how to do a physical loopback on the RME UCX to get many more equalizer nodes.

    What Fx plugins were present in the mix?

    Any plugin relying on time domain shifts, like chorus, flange, phase etc will, by their very nature, introduce random variations every time you play the mix, and they will not null.

    Same applies to synths with LFO's etc

    I figured it was console emulation or Breverb or both. thanks for replying btw.
