For the "shorted" the offset is 3, but the scan index is set to 2. Also the scan index 2 is already taken by the previous channel. As a result the "shorted" channel will appear to be selected if the previous channel is selected and vice versa and it is not possible to sample the "shorted" channel in buffered mode.
