In the game the named characters have an inventory and can equip armor and weapons
A lot of those are literal relics from their own AND other chapters and artifacts that they would have had no way to acquire.
You can get Forgebreaker, a weapon made by a primarch for another primarch. You can get a literal discarded custodes armor, you get find a weapon that was lost 10k years ago after a battle, you can get a plasma pistol (might have been a sword) powered by a demonic heart, etc
PERSONALLY i dont think itsmeant to be taken seriously, but it created the meme that they are the actual items and that the blood ravens as magpies have been retrieving these relics.

Again i personally think its just a problem with the devs and writers going a bit too happy on adding shit with recognizable names instead of creating a full array of new shit or call them just PowerSword +2
