[@SleepingSilence] Like Demon said, you might be overthinking things. I think the general idea of the section is just "what is the arc you have in mind for your character". Just the general idea is all. While it may be weird to have in a CS, I think it's a good idea for an RP with limited participants. It probably helps the GM structure the story as we go to create scenarios and chances for our chars to grow as well as move the story forward.

EDIT: Although, a paragraph seems a bit much just to get that across ^_^;
