The whole message went into the H card and the body both, so a multi-paragraph -m minted a multi-paragraph heading and carried the same text twice. An H card is one token (§4.7.7). The split is at the first newline, not the first blank line, so a two-line message cannot mint a two-line title either.

ls and show read only a title's first line: landings minted before this are immutable, so a reader has to cope with them, not merely stop making more. A message with no title line is refused before the branch lookups and the store scan.
