Repeat action server variables

Hi, I am new to some of the action servers and due to the lack of extensive documentation I am trying and learning through experimentation.

With the repeat action server I have found this curios situation.

I set a value to a variable named count, which obviously generate a variable count. When I set a new value to it inside the repeat action server step apparently it create a new variable count in the inner scope.

Could someone help me with it?
