The obvious alternative would be executing sudo as a user with admin
priviligies. You know of such a way?

The cited article is about Linux, not Unix-flavours like OS X. Not the
same cat necessarily. None of the reason listed on the main page are
really valid in the situation described, except if one forgets to log
out with 
exit [return]
(One can also just close the Terminal window)

As it's obviously would be bad to leave your machine logged in as su.
One could also use "sudo" when logged in with su, for whatever reason.
Some commands demand this even as you are logged in as su.

You have any valid reasons why a person that can log in with su as an
admin user, as he/she has the username/pass, that he should avoid it?
