Stateful NAT question

Hello experts,

I have a question about applying stateful nat. Cisco doc and IPexpert blog
http://www.cisco.com/en/US/docs/ios/12_4/12_4_mainline/snatsca.html
http://blog.ipexpert.com/2009/04/27/high-availability-nat-with-hsrp/

tell to use route-map, like this:

# ip nat inside source route-map rm-101 pool SNATPOOL1 mapping-id 10 overload

Why they do not use "list" keyword instead:
# ip nat inside source list 101 pool SNATPOOL1 mapping-id 10 overload

It looks to me like configuring route-map that only matches an access
lists is just an unnecessary step.
Am I right ?
