While code gives you a correct understanding of the state of the system, it doesn't give you any understanding of why the system is in that state. That's the point from the OP. Code tells you what a system is doing, not why it was designed to be that way. Comments that try and explain what a system is doing can absolutely be wrong and therefore problematic, but there's no way for code to convey the context in which it was implemented a particular way, which is what comments are for. Code without comments only gives half the story. It gives you the what, not the why.
