Not really, it is standard bourne shell (from the man pages):

       Control operators: &  &&  (  )  ;  ;; | || <newline>

It acts as you suspect, so the following constructs would be equivalent 
(I've noticed that most of the ultrix boot scripts prefer the latter method):

    if [ -x "$file" ]; then
        if `$file`; then
            echo "oiy, it ran"
        fi
    fi

Or:

    [ -x "$file" ] && {
        $file && echo "oiy, it ran"
    }
