I think unattended-upgrades only runs once a day by default, and the repository index could have changed since then. Different results on different machines can be because unattended-upgrades didn’t run at the same time, or from the same mirror (and mirrors take a while to propagate changes). Generally speaking you should always run an apt update directly before installing new packages.
