ASA QOS confusion

Hi guys,
 
I need some clarification.
 
This example is from the ASA command line guide:
 
hostname(config)# class-map cmap

hostname(config-cmap)# match tunnel-group

hostname(config-cmap)# match flow ip destination-address

hostname(config-cmap)# exit

hostname(config)# policy-map pmap

hostname(config-pmap)# class cmap

hostname(config-pmap)# police 56000

hostname(config-pmap)# exit

hostname(config)# service-policy pmap global

hostname(config)#
I'm not clear exactly what affect the match flow ip command has. Does the
match flow
command HAVE to be entered when using the match tunnel-group command? If it
doesn't what would happen
differently if not entered?
 
Also, notice the police command. Does that limit apply to ALL the combined
traffic flows thru the tunnel or
is 56000 the limit for each flow to a different destination address?
 
I read the command line guide at this link but I'm still confused:

http://www.cisco.com/en/US/docs/security/asa/asa72/command/reference/m_72.ht
ml#wp1749376

Can someone clear the fog off this command?
Thanks, Tim
