They've scanned that system before, but now that we know there is a smaller planet there that could have life, they can search over a wider spectrum of radio, searching in ways they previously didn't. If there is something intelligent there and they are broadcasting, then it won't be long until we find something. Red dwarfs are also good for life in the sense that they live a long time. There is a good chance that that star will still be around when ours dies.
Edit: Back to SETI, if someone does live there, 20 light years isn't really that far for communication. Sure, it would take 20 years to send a message, and then another 20 to get one back, but who knows, maybe in the 40 years it takes to finish saying hello, one side or the other will end up figuring out how to talk faster. | |  | |  |
