Yes you will have all the data in two nodes provided there is no mutation drop at node level or data is repaired
For example if you data A,B,C and D. with RF=3 and 4 nodes (node1, node2, node3 and node4) Data A is in node1, node2 and node3 Data B is in node2, node3, and node4 Data C is in node3, node4 and node1 Data D is in node4, node1 and node2 With this configuration, any *two nodes combined* will give all the data.
