Yes, Vim checks only the first line for each file.

This error can happen, if the first file does not have a
non-ASCII character but any of the other files has such a
character in the first line. (In this case, Vim expects each
other file to not have multi-byte characters in the first line).

This sounds like a bug (so forwarding to vim-dev).

Also currently, Vim only checks for multi-byte or non-multibyte
characters, but doesn't care whether the encoding is different for
multibyte characters. Not sure, if Vim should do this.
