No, not to be different. Everyone has different structure, and has to maximize the presentation of their physique. Jay really shows SERIOUS muscularity with that type of MM pose..It THE toughest most musclar pose to do , and look impressive doing so.
You try a JayC style Most muscular, then try a standard Most muscular..see what YOU look better at..you will notice the one Jay uses would own you and most of us...because we dont have the mass in the chest, shoulders and arms to look impressive like that..
you're right.. cheers mate
