The problem is that deconstructed started life with a specific meaning, but has been degraded. Far too often, nowadays, it's what many seem to think: that you merely separate the dish into it's component parts.
Technically, that would meet the standard definition of deconstruct. But in culinary terms, deconstruct means to break apart and then reconstruct in a new manner.
Originally, deconstructed could be the epitomy of the chef's art. What it meant was that you took the ingredients, prepared them in a form different from the original, then recombined them again. The look was different, but when you ate the dish you got the same flavor sensation as the original.
For example, I once saw a deconstructed Ceasar salad that used molecular gastronomy techniques to create a totally different look and feel. The dressing, for instance, was turned into a gel disc that flowed apart when you passed your fork through it. Something else had been done to change the form of the Parmesan. Etc.
Visually it was quite striking, and unlike a regular Ceasar salad. But when you bit into it, you knew that Ceasar is what you were eating.
That's a long way from laying out the greens, cheese, oil, vinegar, egg, and anchovy separately. But, unfortunately (and you can blame the TV chefs for this) that's what it's come to mean.
