There is no obligation and they will not reverse it.I know Valve will return your item if you try to sell your knife on the Steam client for $100, but somehow turns into $1, but what obligation do they have if you try to sell it outside their services?
There is an inherent risk selling digital goods and experienced self-sellers and buyers know that a successful transactions requires one of the two to put trust in the other first. Since @HappySticks™ decided to trade first, he is putting his trust to the buyer that they will pay after they receive the item.
The only case I have seen it done is very rare, and it was according to the trader, the client lagged.
