This is actually how you should declare something that you will never change, but something might change externally, like an input pin or status register.
Writing to it might do something completely different or just crash, but you also don't want the compiler getting creative with reads; You don't want the compiler optimizing out a check for a button press because the "constant" value is never changed.
Yeah I stumbled on this too. Surely the joke should be const mutable, not const volatile.
