prec·e·dence
ˈpresədəns,priˈsēdns
noun
1.
the condition of being considered more important than someone or something else; priority in importance, order, or rank.

priority usually means first, but in this case you don't want priority, you want to go second. I'm pretty sure we all get what they mean but the GDC really needs to think through some of the stuff they write in the manual, it's really easy to get lawyered.
