Looking at the time both posts were made, the post he claims to be the original was actually plagiarized from the post made by the user Korkor.
Playing devil's advocate, the time zone in those two forums could be different. :/
I have checked the time from both forums and it seems the post was published here before swiftcointalk.
Edit: I misread this. As I also talked about local time above, I supposed S_Therapist was talking about time zone.
