You must be referring to other poster then; I did not mention at all
the term "call by reference" (or "term by value" for that matter)
exactly because they mean different things to different people. I only
stated that Python's parameter passing is like passing a pointer in C/C
++ and gave a specific example of what I mean by "like passing a
pointer", without labeling it as "call-by-X".

I didn't dispute the validity of the explanation, only its educational
usefulness (both with respect to my posting and in general for someone
new to Python).
