My point is that the leucine content generally is lower in plants and that's a limiting factor. Vegetables have a less ideal amino acid profile. As long as you get enough leucine you're good when it comes to muscle building.
Regarding the study you linked: if you look closer at the nutrient composition the protein intake and amino acid intake is roughly equal between the groups but the vegan group has a higher carb intake, and as we age we all become more or less carb intolerant and that's one of many drawbacks of a pure vegan diet. Other drawbacks are lack of micro nutrients that need to be taken through supplements unless extreme care is taken, and for practical reasons it's not easy to achieve compared with an omnivore diet.
