Yeah, I didn't word that very clearly. The swingarm has greater leverage to compress the shock (or so I'm assuming from photos without actually measuring it and doing calcs). This results in greater axial force in the shock which requires a heavier spring rate. That greater force has to be transmitted to the main frame somehow and would require much sturdier means of mounting the shock, hence HPN's shock "subframe" with three points of connection to the main frame.
