Yes, steam is responsible for refunding. In EU there is protections like this so you are allowed 14 days (if I recall correctly) to return an item bought online because you had no way to review it "in person". If you consider this law sans Internet it still makes 100% sense. It applies to phone-ordering from TV shopping channels, or mail-ordering as well. It keeps merchants honest for at least 14 days of products use, forcing them not to (re)sell items that will quickly disappoint. It overall makes it much easier to be a consumer which should be in everyone's interest.
