Yes but... that's not the topic. It's why does the LH arm come loose more often then the RH one. For pdlamb to be correct then we need to believe that all RH arms are installed correctly and some LH ones are not. This is IMO not likely as the RH install methods to be perfect so many times but the LH side not so doesn't seem likely, both being dealt with by the same factory and shop assembly standards (or lack of...)
