I got tripped up by not reading it correctly.
Remember that a prefix list and a route map both have an implicit deny at the end of their entries.
The prefix list is permitting the host prefix so it can be processed by the Route map. And it intentionally leaves the implicit deny because the Route map only processes that host in order to deny it. However, the Route map implicitly denies everything else, preventing other routes from being installed in the RIB

Take a look at the route-map command where it includes the keyword "deny" statement. If you were to add a second prefix list entry (seq 15 for example) permitting everything else, it would still be denied because of the route-map key word "deny."
Adding a second route-map entry with the key word "permit" would be the better option. Remember that if you have a route-map without any "matching" keywords, you match all traffic by default.
