I believe it does cause the link to flap because this changes the ospf
database. When the database changes it will dial to send these changes to
the other side. The database continues to change because the host route
keeps being inserted and removed from the routing table as the link goes up
and down. One causes the other. So when you add the no peer route
statement, it prevents this from happening. I agree that ppp is what
inserts the host route.
