Fix code regarding to console output log (#37754)

I could change the console output but based on the other part of the code it seems the code should be changed.
So the snippet is talking about ``ref parameter `` and first creates an object with ID ``54321`` and then seems to want to change ID to ``12345`` to show the case.
