From the closest point on the pitch to where the foul occurred.
So on the touchline? (in this particular case) That's what I would assume.
Didn't happen in this case; players looked rather confused, ref just jogged off to his usual position near the "D", and eventually the attacking side took the freekick from a metre-or-two closer to the goal than they should have!
(No big deal, but they DID gain an advantage ... )
