As mentioned above, your Order hasn’t changed but by choosing to stay together with another player as you do the story, it’s kept you on their storyline. There isn’t any way to go back and redo that section of the story, but future storylines (typically at each chapter break) will once again go back to your Order’s storyline if you don’t accept the progress of another player and follow their storyline. More specifically, when doing the final story mission in a chapter, do not accept the progress of a player from another Order, or it will put you on the same storyline as them for the next chapter.
