Those two dicts are *class variables* not *instance variables*!

That clears only one dictionary at class level. Which is visible on both
instances.
class Distribution:
def __init__(self):
self.__gr_on_transp = dict()
self.__ostatok_m = dict()
...
This creates *instance variables* which should be deepcopied without
problems.
