Yes, a router is free to choose whatever path it thinks can reach the Data.
Forwarding strategy is the component that makes this decision.
However, if the Data has been retrieved from face1 and is still present in
the local cache, the router would return the cached Data when the same
Interest arrives the second time, instead of forwarding the Interest again
