Cos just adding stabilising chems won't stop an active ferment. Just prevent a finished one restarting when more fermentables are added.
Anecdotally, it does seem then only way to actually stop an active ferment is to cold crash, then while the batch is still chilled, to rack it off the sediment onto the stabilising chems - even then its not guaranteed but the most likely method for success.....
