Not familiar with the situation(s) you are talking about, but its generally a good idea to be polite when entering corsair space, even if it says "ally" in the rep list.
Like... dont be all
"I can go here cause we is allies noob lol"
when you enter gamma.
More like:
"My beloved hermano ally. Would it cause you inconvienence if I travelled through your sovereign territory? You dont want me to? Ok dear friend, I will take another way. I still love you anyway."
Also, I think there will be no corsair/order alliance in 4.86.
