If you look at when he does the hand clasp MM pose, he makes himself narrower because he brings his shoulders in. This shows with that pic of Nasser and Dillett and Dillett is doing the hand clasp pose. Ruhl modifies pose the with knuckles together and elbows out, thus flaring the elbows and shoulders out. This also shows in the Dillett and Ruhl pose.
Also, when Shawn Ray does this pose, it makes him narrower as well, because he brings his shoulders in, just like Dillett does.
