I think it makes sense. To change a lightbulb procedurally, you would do something like $lightbulb = changelightbulb($lightbulb); whereas the oo way to do it would just be $lightbulb->change()

The whole idea behind "You're still thinking procedurally" is that rationally you are thinking of how to change a lightbulb so you can figure out how many programmers it takes when really, you shouldn't care how it happens, only that there is a method (change()) that takes care of that for you.
