Yes, but that's more by accident than by design.
It's not always clear what's the "right" thing to
do with reference counts when casting to or from a
Python reference.

I'll look into this case and see whether anything
can be done to improve matters, but I can't guarantee
I'll be able to fix it without breaking some other
usage.

Probably I should add a note to the docs about this.
I thought I had already mentioned it somewhere, but
it seems not.
