Assuming your time field is a numeric timestamp, the sort will put the events in descending time order i.e. latest first. The dedup will keep the first event in the pipeline for each table name.
Without seeing the exact data you are dealing with, it is not possible to say whether the values you are showing are correct or not, but given the above assumptions, if you are not getting the data you are expecting, you should look closer at your actual data to determine where the discrepancy may have arisen from.
