Thanks for pointing this out. We'll get it fixed. (Going to mark this as "Resolved" as we'll get the change out this week.)
EDIT: Just a quick note: I think the idea is there in that KB, but it's just not clear. Forcing Two-Step means that it can't be enabled on individual users. I think that's what was meant by the statement referenced. Regardless, we'll get it clarified to avoid any confusion.
