I swear I've seen in this forum a diagram of another pedal with this same topology, but I can't remember its name, nor in which section to find it...
Even the article had the oscillograms of the waveforms at different points of that circuit.

Reminds me of the differential distortion.

You're right !!!
It's similar in concept to Dinosaural tube bender.
