They are different. In the case of Live patching, you are replacing
small portion of the hypervisor with a new version. This works quite
well when the changes are not complex and doesn't require to mutate your
data.

In the case of live-update, the existing hypervisor will be replaced by
a new version without requiring a restart of your VMs. This would allow
you to upgrade between stable release (and possibly major) versions of Xen.

So far, only live-patching is available upstream. But there is plan to
get live-update support for Xen.

Best regards,
