It can be a benefit or a cause of problem. In one end, it could lower your noise. The DG535 actually has that as a recommendation, that the signal source and the DG535 operate on the same clock.
Another aspect is that you keep banging the same little range of values, and that may for that time-base to stop delay be systematically off in an unfavourable fashion. The noise of a counter is not always linear with that delay, so an asynchronous clock would sweep over the range. Then again, if the delay is just right you can utilize the minimum.
