Why is this inside a $()?

I am just wondering if this is more portable and readable...

	... &&
	current="$(ls -l .git/info/refs)" &&
	case "$current" in
        -r--r--r--*)
        	: happy
                ;;
	*)
        	echo Oops, .git/info/refs is not 0444
                false
                ;;
	esac
