There were 2 objects with different Physic Materials: A, B
A moved on B acting as ground
In each case only!! the Friction Combine Mode was changed
FCM - Friction Combine Mode
DST - distance travelled over time T
The combine modes in order(the numbers between the parentheseses below correspond to these):
I sincerely think I'm right that the cause is the combine modes' order where later ones have higher priority and thus overwrite the ones with lower priority and the friction value used as the friction value for the friction between the 2 colliding objects is determined by this single combine mode.
My problem is that I haven't heard anyone mention this and the bigger problem is that even now after a quick(too quick) googling I didn't find any mention of this.
To make it so that noone may say that this should've gone to the forum instead let me make a few simple questions out of all this.
Am I right? Why haven't I found any mention of this phenomenon? Should one know this off the cuff?

This is undocumented functionality.
From my tests, the friction combine mode used uses the largest PhysicMaterialCombine in the PhysicMaterialCombine enumeration of the two materials.
The enumeration is something like:
and the combination function for let's say dynamic friction would be something like:
I believe it is also the same for the bounceCombine.
