How to replicate this: 1st time buy extra spirit, then upgrade it to improved spirit. 2nd time buy improved spirit. Pick any hero that has spirit scaling on his ability and test damage. 1st case deals more damage than 2nd even tho stats are completely the same.
My case: I picked dynamo and tested his 1st skill damage(no AP spent, only 1 item bought). 1st case: he deals 150 dmg. 2nd case: he deals 145 dmg.
Same probably happens to Vitality and Weapon items. You get more stats by getting the same item when you upgrade it. If you rush the upgrade and skip lower tier part of it you get less stats
