On one hand, I think it would score a point, because the player made an effort to incorporate fiction into the ability when he isn't actually required to do so which would imply an interest in the fiction.
On the other hand, what if the battle is taking place in a jungle (to be extreme) and the player declares there's a rug on the ground? Does that mean he genuinely believes that there are rugs in the jungle, or is he just throwing out an excuse so to speak to use the mechanic? And if he did make up a limp excuse, does that make it any less legitimate?
I think another mechanic of FATE might be interesting to you. Players have the ability to make Declarations that define aspects of the scene. I'll paraphrase an example out of the Dresden Files RPG book, which uses the FATE rules (they're OGL). In the example, a character is being chased by vampires and makes the Declaration that there are pipes full of running water in the area. The GM sets what amounts to a DC for his skill roll (in this case Alertness) and if he succeeds, they are there. If he doesn't make the roll they aren't there. In the setting vampires don't like running water.
So this is a rule in the system that allows players to mechanically define a scene with a set difficulty to beat. In D&D, scene definition is something completely under the purview of the DM. But, in other games, it can be a shared role between players and game masters. As traditional roles blur, so can the feel and mood of the game shift. When you play the Dresden Files RPG, it isn't like playing in D&D, but you feel like you're a living in the world of the Dresden Files novels. It's trying to evoke a different experience, and the conceits of the game reflect that.
My take on the whole disassociated mechanic issue is that a game is much better if it doesn't have to use them.
Eliminate the problem that causes the need for them and then they can go away.
That's like saying "I don't like chocolate, so we need to kill all the cocoa trees!
Maybe Dungeons and Dragons 4e is better for its dissociated mechanics for some.
