 This is documented as the way the spindown command works.  From
 atacontrol(8):
 
 spindown   Set or report timeout after which the device will be spun
 down. To arm the timeout the device needs at least one more request
 after setting the timeout.  To disable spindown, set the time- out to
 zero.  No further actions are needed in this case.
