I'd agree.. but in situations where you're given facts which are almost but not quite identical to the facts of a previously decided case, it is often useful to analyse the facts of that case in greater detail than you would otherwise. It gives you great scope to suggest that the case could have been decided differently - the difference between the two sets of facts will often go to the root of the issue.
However, as everyone else has suggested, it's usually a waste of words to summarise facts - you'll either waste too much of your word limit on reciting irrelevant detail, or over-summarise and miss a material fact - neither gives a good impression. Sometimes I do feel, though, that a footnote is useful (particularly if you leave them out of the word count!) - to say something like 'in this case the subject matter was X and so in line with previous decisions the court was more likely to hold that consideration was past rather than to follow the more recent approach applied in cases where the subject matter is Y'.
I've written way too much but can't be bothered to edit.. basically on the whole just state the principle, but it doesn't hurt to mention facts concisely but accurately if they are particularly relevant or useful in getting to your conclusion. Good luck!
