Charlie used Decred for his 2017 LTC/BTC atomic swap?  Is this 100% true?  Surprised if true.

I asked because he did 2 atomic swap posts in 2017, one mentioned decred, the other did not. 

This one mentioned decred: https://twitter.com/satoshilite/status/910534107058233344?lang=en (5:00 PM · Sep 20, 2017)

This one does not: https://twitter.com/satoshilite/status/911328252928643072?lang=en (9:36 PM · Sep 22, 2017)

Do we know if the Sep 22, 2017 was done with or without decred?
