This study seems awfully limited (16 people!), so may not mean much. However, it's pretty well known that animal protein is higher quality than vegatable protein (by the amino acid profile.) You can't just compare grams of protein on the back of the container. So it wouldn't be all that surprising either. For me personally, I've tried whey protein powder and the vegan stuff (the good, expensive stuff.) I get better results on the whey. I also tried beef protein powder. It's disgusting, I don't know if the gains were any different from whey, but it's not worth it!
