Thanks, Jorg. It seems to me that the description in the second post you quoted is the correct explanation.
– I will go through both posts carefully and revise one. I will comment here when that is done.
– Thanks again for pointing out the discrepancy.
P.S. When asking a question on a specific post, please have “Post on ‘Title of the Post'”
– I have revised the title of this thread accordingly.
– Otherwise, the thread could be confused with the post itself.
