They used to stack, but as of 6.14/15 they made them unique passives, meaning that they no longer stack. If you want test it just make a custom game with a friend and check your stats.
As you can see, they have different names though they do thee same function. Maybe read the items' descriptions more before you say who is "outdated" between you and Jani?
But they aren't named the same. Unique passives without names mean that they don't work if you have two or three pieces of the same item. The unique passive doesn't have a name so they still stack.
