I never wrote too many C or C++ on the desktop, but often ended up refactoring my embedded code from one style to an other. After a while I realized this is simply my way of understanding the code better, and making sure I haven't missed anything. The direction (inlining or breaking things to functions) almost doesn't matter. What matters is working with the code. It's not so strange If you think about it, designers understand things by sketching and taking notes, that's why you see designers run around with their moleskins.
