See the docstring of string-to-multibyte: it's basically equivalent to
(decode-coding-string STRING 'binary).
If you want your unibyte string interpreted as a latin-1 encoded text, then
say so explicitly:

  (decode-coding-string (concat "\300" "\310") 'latin-1)  =>  "ÀÈ"

> (concat (string-as-multibyte "\300") (string-as-multibyte "\310")) =>
> "\xc0\xc8" (why ?)

If you don't know, then please pretty please, stay away from
string-as-multibyte.
