Upgrade will upgrade the system to whatever is newest in your package cache. If, for example, you’ve just performed a partial upgrade and put yourself into an unsupported state, running upgrade without first running update will put your system back in line with itself.
There probably almost never a reason for this, but its the equivalent of running pacman -u which under normal circumstances you will never do
I’ve never understood why the update part isn’t included in the upgrade command, since upgrade is useless without it
