I've shot all their models with the omega cam with the exception of the Super Nova. When the stop on the lower cam module hits the string, I can easily pull another 1/2" or a bit more. If you have a draw stop that hits the limb, there is no pulling through it without moving the limb, which is very difficult to do. When using back tension and pulling, this becomes very obvious to me. Several of the guys shooting Merlins at the local shop have said the exact same thing to me. Don't get me wrong. I don't see this as a negative. I don't like the super hard walls I've felt on some single cams. In fact, I sold my Diamond because the wall was simply too hard for my liking. The other night when the six of us were shooting the Max Extreme, the 3 that preferred the Machete, specifically liked the harder wall.

I suggest you take do this test (I have) Get somone to pull the max extreme until the string hits the draw stop. Then have them pull into the stop with about 10-15 over the holding weight. Notice the movement on the lower cam. It's quite easy to make it move more an inch or so. I'm surprised you haven't noticed this. It caught my attention on the very first Merlin I ever shot (I've only shot the Omega cams). For me, this makes a back tension release easier and it just feels better to me.
