Can my familiar reload my crossbow for me?

I’ve seen at least one online character optimization guide suggesting that low-level alchemists should acquire a familiar for action efficiency with crossbows – specifically that you could have the familiar reload your crossbow for you, thus allowing you to consistently get off two shots per turn (you command, you fire, familiar reloads, you fire, familiar reloads). This seems dubious to me, but I realize that my grasp of the rules is still imperfect. Does this work?
