i was offering examples as to how i know the system works the way it does.

if you are wearing that gear set when you save it, it will have the class/job initials and the item level. if you equip a weapon for a different class and save it without making a new gear set, it will save over the class that you started as. if you make a new gear set, all of the hotbars will save the way they are set for that class. hotbars 4_8 which are in a colored square are locked hotbars, so every skill thats put there, will be there for every class.

i figured this out because i put potions on hotbar 8 while playing as monk, then moved to WHM and the potions were still there, and i didnt need them.
