@m_adam Thank you for the confirmation and the reading suggestions.
Just for context, this is a general conceptual question and not connected to a specific code issue. I noticed the behavior while doing some test scripts with id() and is. It is worth noting that these Python properties need to be used carefully in concert with C4D objects.
(I wouldn't exactly recommend using pointer comparisons in C++ either π )
I will include an "advanced" chapter in my Python/C4D book to mention this.
