They attribute this to the fact that they send less data (everything, including the headers, is compressed), and also to the fact that they have only one TCP connection. Apparently it's very bad to lose a SYN packet, so it's advantageous to them to reduce the chance of losing one by opening fewer connections. See the section entitled "The role of packet loss and round-trip time (RTT)" at [1].
