Assuming that most people will run their FAT16's near the max of the capacity, they will have large clustersizes (16,32 or 64k) A FAT32 of the same time will then have 4 or 8k.

Note that not every fragmentation is a drive movement. Cylinders are probably also way bigger. So if the HD driver tries to place fragments near, it will still be read/written in a single spin.
