The line makes it a possibility that Lando was not on Pasaana when Leia sent him a message. She sent it because she knew about his previous experience there with Luke. So he travels to Pasaana, gets in a taxi, and finds the heroes to fill them in on what he knows.
With the line removed, it is heavily suggested that Lando has pulled a Luke Skywalker over the past 20 years and has given up on everything. He is rotting away on a desert planet, and hasn’t left it since he was with Luke.
