No it doesn't. (equal (string-to-multibyte "A") "A") => t.
There is no deep reason for the current behaviour. It's just how things came to be, and nobody has been sufficiently annoyed to change it. The implementation is efficient and good enough for most purposes.
It is inconsistent and confusing though, and occasionally it does break down. One such case is when two strings that are not 'equal' become 'equal' after printing and reading them back, since unibyte and multibyte strings have the same printed representation. This can arise in conjunction with byte compilation.
Again, I have no plans to do anything about it right now.
