(He did lose parts of his memory sometimes before, but Tom fixed that somehow and restored his full memories to him fully in Whiterun. So that should no longer apply.

From Bouros' CC:

"Curse of the Neverending Death" - The children of Satakal are cursed by their father to do as the God did to the worlds: die and reborn. Every day of their lives they suffer a painful and horrible death only to be reborn a few moments later, refreshed and well. This process is very tasking and as such it might implicate in a loss of memory of those cursed by it.

There is no mention of his soul being "renewed" as you claimed. From the description, his soul is still fine after he dies it's just his body that gets reborn every day. That being the case, the Chains of Domination wouldn't just disappear after Bouros dies that day.)
