THIS is how I learn the Pope died?!
Though I agree with you, the whole affair has been awfully suspicious.
I think cases of important people dying and the public being lied to about when and how it happened are very common
Some personalities have enough power and influence to have people under them force this stuff to be altered for media or political purposes, putting on appearances, or just to seem nicer and more presentable
In fact death records are being changed all the time even for non famous people, but with civilians they don't have the power to affect it, so it's just up to whatever is necessary at the time
Like during the Covid disaster, lots of people who happened to have the light sniffles when they died were recorded as dying "from Covid", even if they fell off a ladder and busted their skull or died of a preexisting cancer, if they died 'with' Covid, they died OF Covid, that's that! And at times when their families would intervene and claim otherwise, they were strong armed into accepting the narrative and stating that, yes, their relative DID die of Covid, or else they won't get the body back for the funeral
Interestingly, 'last words' are also often times wrong, but for less nefarious purposes (Well, there ARE cases where a person's last words just so happen to be an admission to a crime they didn't commit or getting an important person off the hook, or just stating something that would support a current narrative, which coincidentally only the interested parties heard and now nobody can ask them otherwise or disprove it. Hell, they even did it to Koko the fucking gorilla! But still...), most cases are not malicious or conspiratorial in nature, just nurses in hospitals wanting to give the patient's family a nice flowery sounding phrase to end off on a good note, because very commonly the patient will say some real Last Words^tm material like "Tell my family, I'll always be looking down on them and smiling!" And then follow it up 15 minutes later with "Aw fucking shit who farted in here?" and keel over, making the nurse decide it's better to leave the last bit out
