From what I remember from my Jessica training many moons ago, Top priority is the top coat and should be used to seal in your colour coats. brilliance is a high shine gloss, is optional, and should go over top priority for extra shine. Perhaps this is why it is disturbing the colour coats. It is thicker and needs top priority to colour lock first.
With regard to the older posts, for anyone else wondering and not aimed at anyone in particular, If you cover completely with your top coat, finish or whatever your brand requires, it shouldn't remover any colour when removing tacky layer. It is very easy to miss bits as I have recently found out using the additives. I thought I was very thorough with my shellac top coat but obviously have been a bit slap dash!
