I think that these ideas are both compatible. In this blog post, it looks like the author finished working prototypes of several games but elected not to push them to a full release. So I think they “finished” the work, and we can’t fault them for estimating that it wouldn’t be worthwhile to make a full release. Not finishing a project in this case would be abandoning a game idea that you liked before you even got to a working prototype stage. Because then you can’t even see if your new idea plays well.
