Exactly. You only write code sequentially when it's a new file. If i decide to add a new field to some class, i won't necessarily go to the class definition first, I'll probably write the code using that field because that's where the IDE was when i got the idea. If I want to enhance some condition checking, i'll go through a phase where the piece of code isn't valid while I'm rearranging ifs and elses.
