What CL are you reading at ? Write ops go to RF number of nodes, read ops go to RF number of nodes 10% (the default probability that Read Repair will be running) of the time and CL number of nodes 90% of the time. With 2 nodes and RF 2 the QUOURM is 2, every request will involve all nodes.
As to why the pending list gets longer, do you have some more info ? What process are you using to measure ? It's hard to guess why. In this setup every node will have the data and should be able to do a local read and then on the other node.
