Why do you assume the same tractor beam moving the pod and moving people into the pod?
My read is this. Tractor beams are described as a field effect devices - the grab is not a "point" source, as a physical shove would be, but a uniform field, like gravity. The same gravity that holds down my car still allows me to stand. You would need to limit the Field to what a person could handle - 3-5 Gs usually, 9 gs max, unless the pod had a working compensator or grav plates. (which would probably be a power hungry device that would be turned off as soon as the pod was clear of the launching ship)
