I don't understand why this happens (often enough to be a serious problem). Uber should be motivated to catch and stop this because the extra revenue from the scams is almost certainly not worth the loss of users that will result. It should also be easy for Uber to detect this since they collect location data from both phones. Sure, one of the two could be faking the data, but they could check both traces for plausibility (this might be why they collect location data even for a few minutes after the trip has ended - to get a baseline), and even if they don't apply any advanced smarts, it should be easy to check whether a driver got caught doing this repeatedly with unrelated customers. Is it just drivers trying it without realizing that it is unlikely to benefit them in the long term, or Uber being bad at their job?
