Stamina Questions

So, I've been looking into the Stamina is used in Evasion flag and I'm not understanding step 5b. Would someone please run it down for me?

Step 5. Check to hit for attacks that can be blocked by Stamina

   Most attacks use step 4 instead of this step. Only Break, Doom, Demi,
   Quartr, X-Zone, W Wind, Shoat, Odin, Raiden, Antlion, Snare, X-Fer, and
   Grav Bomb use this step.

   Step 5a. Chance to hit

     1. BlockValue = (255 - MBlock * 2) + 1

     2. If BlockValue > 255 then BlockValue = 255
        If BlockValue < 1 then BlockValue = 1

     3. If ((Hit Rate * BlockValue) / 256) > [0..99] then you hit, otherwise
     you miss.

   Step 5b. Check if Stamina blocks

     If target's stamina >= [0..127] then the attack misses (even if it hit in
     step 5a); otherwise, the attack hits as long as it hit in step 5a.

Does this mean that if the target has a stamina value greater than or equal to  a randomly generated number between 0 and 127 then the attack misses?
