I would assume this was done to prevent the subjects knowing the fat content of the different diets as this may have influenced the amount they ate.

According to Appendix A they used olive oil, high–oleic acid safflower oil and safflower oil margarine for both diets.

3. 25% overconsumption was required.
No, an extra 25% was offered but it's consumption was not required -

"The diets offered contained 125% of the estimated energy requirement to allow self-selection of food quantity"

4. low fat diet had much more fiber
Unavoidable and addressed by the author -

"A low-fat diet will generally be lower in saturated fat and cholesterol and higher in dietary fiber than will a high-mono diet, so that the composition of the 2 diets in our study likely mirrored the composition of these diets as they would be eaten in the "real world.""

5. refined sugar was 10% in both diets
Not ideal I agree but it does reflect the real world diets of overweight diabetics and as it was the same for both diets it wouldn't have influenced the results.
