A quick quastion about Loop Action

A quick quastion about Loop Action

When I use this trigger:
"For Each Integer A from 1 to 12, Do Multiple Actions"

Do action happen in turns, so first 1 then when 1 finishes 2 etc.

Or do all 1-12 times happen AT THE SAME TIME?

All at the same time. I dunno how to let the actions activate after eachother

Loop - 1 to 5
   -show message (Integer A)

will do exactly the same thing as putting

-show message "1"
-show message "2"
-show message "3"
-show message "4"
-show message "5"
