Last but likely the most important fact is that he's been a hologram and likely old footage has been used for a while so he's likely long dead and they like with Bin Ladin they have to release the news but not that he was dead maybe even before Russia attacked or even a year or more before. They faked it earlier so they could run the war and spend the cash and push the narrative. Yeah they'll use this faked post assassination to push another part of the narrative.
