I guess they just wanted to make sure the link did not start without
bothering to chase little problems that trigger LSA updates and so the
Fact is that a proper config with OSPF demand will keep the line quiet
when the routing is stable, without that filter.

Without it, the receiving end would clear the line after the standard
2 minutes timer even if there is valid traffic going on.
Then the originating side would dial again, for another 2 minutes
talk, and again, and again...
