Well, it was also known the fact that Minato used the Dead Demon Consuming Seal to seal Kurama and himself away. Even if Minato had to split Kurama in half, the people could've easily imply that Minato sealed the full Kiuubi within the reaper.I don't thing anybody except for the higher ups experienced ninja would've question Minato's ability to seal the full Kurama or speculate about the jutsu's limit. It could have been a believable story.
