What use are ospf demand circuits when you have dialer-watch?

Hi folks,

If you're using dialer-watch in an OSPF environment, and have the
following lines for interesting traffic:

access-list 101 deny ospf any any
access-list 101 permit ip any any
dialer-list 1 protocol ip list 101

then why would you want to configure OSPF Demand Circuits? Shouldn't the
first statement of access-list 101 do the same thing i.e. deny OSPF
Hellos and LSAs from bringing up the link?

Thanks.
