I guess he simply meant :@r (:h :@, do not confuse this with :h @).
And this is general problem with any :execute-like functionality:

:execute
:@
-c
--cmd
py vim.command

: you cannot use continuation anywhere here because all these commands
mostly execute *one* line *always* (and even if they do something else
like ex_at does, used fgetline function still does not support
continuation). And `\n` is being treated just like `|` is.

Though I would say that fixing this anywhere, but in :@ is definitely
going to break backward compatibility: because of "execute one line"
functionality is used to do things like `execute 'normal a' .
multiline_text` to append multiline text or `:execute 'python'
constructed_multiline_script`. :@ is separate because it the only
thing which actually does execute multiple lines, so making
`getexline` used from ex_at (this is essential, ex_at is not the only
place where it is used) support line continuation will simply get rid
of E10 errors.
