Well, perhaps it's not a bug that it executes only one normal mode
command, but why would it insert the rest of the mapping into buffer?
Is that a useful or expected behaviour under some circumstances?

I would say the expected behaviour would be to run the mapping..

It refreshes screen line numbers in signs column (my linenums plugin).

That's great, I modified it a little bit because I have dozens
of these commands:

function! s:WrapLineNums(cmd)
exe "normal! ".a:cmd
call LineNums()
endfu
nnoremap <silent> zz :call <SID>WrapLineNums("zz")<CR>
