The command
autocmd! BufWritePre * call StripTrailingWhitespace()
Removes all autocmds for the event BufWritePre and the file pattern * from the default autocmd-group and sets a new autocmd for this event and pattern to call StripTrailingWhitespace().
Example:
autocmd BufWritePre * echomsg "First"
autocmd BufWritePre * echomsg "Second"
If you then enter :autocmd BufWritePre you will get the following (plus maybe other autocmds defined for this event):
--- Autocommands ---
BufWrite
* echomsg "First"
echomsg "Second"
Then you execute
autocmd! BufWritePre * echomsg "Third"
followed by :autocmd BufWritePre and you get:
--- Autocommands ---
BufWrite
* echomsg "Third"
So the autocmds echoing "First" and "Second" were removed and the new autocmd echoing "Third" was defined.
See :help autocmd-remove.

So does that mean there's not need to wrap my autocmd(s) in an augroup if I'm using the autocmd! cmd version since the previous autocmds will be cleared from the default/global group anyway?

I think I got an answer to my question. As long as you don't have a shared event between more than oneautocmd!command, you're fine withoutaugroups. Otherwise, shared eventautocmd!s will clear each other. So, wrapping yourautocmdcommands inside anaugroupis the safer option here.
