Reset vs Held in While Iterator Simulink

Hey,
I am new in Simulink programming and I am quite struggling with the distinction between Reset and Held for the while iterator.
The picture I attach shows the simple model diagram whose purpose is to count until 100 (external condition) within no longer than 20 iterations. If I set "reset" in the function block parameters, I get "out1 = 14" and if I choose "held" I get "out1 = 1". My question is why? I understand that with "reset" the iteration counter always resets to 1, so why "out1" is not always 1? Why "out1" increases up to 14 if we are always resetting the initial blocks.
I hope I am clear enough.
Thanks, Rodrigo
