I had an exchange of e-mails with EUROCKOT on this very subject yesterday (Monday) because the web site does say that the Briz-KM stage is to perform a "complete de-orbit", and of course it is still in orbit. The reply was the "de-orbit" now seems to mean not to bring out of orbit to re-entry/landing but simply to remove from the operating orbit, and it is in this sense that Briz-KM was "de-orbited". I have suggested to EUROCKOT that they might like to word their announcements more precisely in future because in more than 40 years of following and writing about spaceflight "de-orbit" has implied atmospheric re-entry, etc. I would seem that a similar abuse of the "de-orbit" term is used got GEO satellites. When removed from the GEO band - either up or down - they are "de-orbited". Perhaps I am just old-fashioned and too pedantic ......

I don't know why so many corporate mail servers feel impelled to attach a disclaimer to the bottom of every e-mail message saying otherwise. If you don't know either, why not e-mail your corporate lawyers and system administrators and ask them why they insist on contributing so much to the waste of bandwidth ?
