I think that I have shown, that only an author actually knows what he means.
No one is arguing that. It is simply that it's up to the author to convey that using words with commonly accepted definitions and, where no, clearly state what you mean, otherwise you are causing and inviting confusion. If you choose not to clearly state what you mean and decide to attempt to re-define words with no good reason, you will, of course, be challenged on it.
