The difference between those two things is enormous.
It makes sense that fans would over analyze the minute details of the most iconic prop in the entire series, not to mention arguably the most recognizable and beloved props in all of film history. I'd say having a hand in something like that would be worth bragging about, if you were the type that felt inclined to brag at all, much more so than a digitally rendered prop in a throw away moment from a scene most fans disliked.
Now could it very well have been a joke or a means of self promotion, sure. I just don't find the humor in it. At least if it were self promotion, I could wrap my head around that.
Then again this isn't the end of the world or anything either. It's just Twitter. I loathe that platform more than anything else in this instance.
