In elisp manual(node 11.10.1 `Introduction to Buffer-Local Variables'), it says:
"When a variable has buffer-local bindings in one or more
buffers, `let' rebinds the binding that's currently in effect."

I don't understand what `rebinds the binding that's currently in effect' means, can anybody help?

It is explained in the same node you're referring to, in the beginning:

`A buffer-local variable has a buffer-local binding associated with a
particular buffer.  The binding is in effect when that buffer is
current; otherwise, it is not in effect.  If you set the variable while
a buffer-local binding is in effect, the new value goes in that binding,
so its other bindings are unchanged.  This means that the change is
visible only in the buffer where you made it.'

There's nothing to add here...
