freeswap in sar -r output

Hi Everyone,
man page of sar(1) says:
-r Reports unused memory pages and disk blocks:
      freemem      average pages available to user processes.
      freeswap    disk blocks available for page swapping.

But the blocks of freeswap(84559894) are more than the total swap blocks(67120880):

# sar -r -f sa06

How to interpret this dependency?


Thanks,
