What you have to do is use Sylveon with Cute Charm. Lead with him, switch to a Pokemon who knows False Swipe, and chain like normal. Occasionally use the other Pokemon to False Swipe a new Salandit to keep the chain going.
There were some people mentioning that you just need a fainted Sylveon at the front of the party, but in my personal experience, Cute Charm's effect only seems to work in SOS if Sylveon is alive and on the field.
