Isn't that what would be expected?  It's a combination of

- the canonical representation of a newline is LF, so the repository
  stores LF

- with safecrlf, checkout converts LF->CRLF and add converts CRLF->LF

So from the user's POV, running

  git add withlf.txt
  rm withlf.txt
  git checkout -- withlf.txt

would appear to replace LF with CRLF in the worktree. That's what the message says.
