Apparently it's when it connects. I usually end up using it after the next cast since you are about halfway in when you get the proc. Either they need to change it to on cast completion it procs, or allow it to stack instead of having travel time + hitting the target before you know you have it. Finish your cast, use the proc, and I guess accept that you will sometimes miss the chance to use every proc.

If it procs while you are casting, you finish the cast, then, white the next fire 1 is in transit, insta-cast fire 3, can you launch that fire 3 in time for the fire 1 you were casting to trigger a new proc?
