What is the difference between using multiple -c options and concatenating the options with newline as the separator? (autocmd)

The following vim command lines show different results. Could anybody
help me understand why there is a difference? Thanks.

$ vim -T dumb -c autocmd\ BufWrite\ \*\ echom\ \"Writing\ buffer\!\"
-c w -c messages -c q
