The original post asks the reason for the difference in the status
between the following two cases:

if ((0)); then :; else echo "here \$? is 1"; fi
if ((0)); then :; fi; echo "but here \$? is 0"

and the answer is that the former returns the status of ((0)) (which
is $? = 1), but the latter returns the status of the entire
if-statement (which is $? = 0 because no branch is selected. If any
branch was selected, it would've been the exit status of the last
command in the selected branch).
