menu indications of key bindings for remapped commands

[Drew Adams]

What is the reason that a remapped command in a menu item has its key
binding listed as, for example, "(<remap> <switch-to-buffer>)"? Is it
because it would be impossible or difficult to pick up one of the final keys
that it is actually bound to - e.g. "(C-x b)"?

I assume this is not an oversight or a bug - I'm just curious as to why this
appears this way. It is not especially useful for users to see this, IMO.
