I don't remember this particular game either and didn't watch replay now, but I know stalky likes casting starfall (the first starfall hits enemy from far) and then he leaps immediately after casting starfall, landing near him, for the second starfall to hit.
It works because starfall takes into account the position you are only at the end right before second starfall lands, not the initial casting point of starfall, so basically you can use starfall 2000 range away too (obviously first one won't hit), and if you dagger forcestaff and leap all shifted, fast, landing near enemy at the end of it, the second starfall will hit him. (that's a bit more stylish
