Correct: the packet size distribution over any aggregated Internet link is typically bi-modal: a peak at around 64 bytes (acks) and one at around 1500 bytes (transfers that fill the MTU).
The article seems to me very approximate.

Also, jumbo frames are technically not Ethernet. The IEEE revised the 802.3 spec to increase the maximum envelope from 1518 bytes up to around 2000 bytes to accommodate VLAN stacking and other encapsulating schemes. But jumbos -- usually 9000 or 9216 bytes -- aren't legally Ethernet.
