Configuring a link as "point-to-point" means that OSPF skips the BR/BDR election, making the calculations a little simpler. Normally a multi-access media (like Ethernet) means the SPF algorithm has to use a "trick" to build a graph, since all graph links must exclusively be between two nodes. Electing a pseudo-node and treating the multi-access media like a star topology solves this, but makes the SPF graph more complex.
