Saying it doesn't count is rejecting a huge chunk of the game.
Yes, I would count it separate. If we are to include it it would be too early to say who can possibly be the main protagonist for 6.x as we haven't seen the entire plot.
It may as well be Zero, or it can even be Golbez. To me the plot in each post-credit is quite disconnected from the pre-credit.
