In other words/ questions: Let's say i pull the columns, so the elevators moves downwards, i use trim Up to compensate the forces needed to keep the pitch.
Will the columns stays in that position, even when the forces trimmed away, or will the columns move back step by step to the previous neutral position while trimming?
you pull column elevator moves up not down. You trim the stab to align with elevator i.e you use trim switch up but actually the stab moves down and then release the column. The neutral position of the yoke remains same.
