I think the assumption is also that all else being equal, yes, it glass elements will be bigger to accommodate a larger sensor, but the lens as a whole can still be light by using lighter metals like aluminum and perhaps less glass elements.

For the same material, the larger the sensor, the more light collected, the smaller the light gathering element is needed and the smaller the lens.
