[opensuse] zypper patch vs zypper up?

All, I upgraded my desktop to 11.3 months ago via "zypper dup". Since then I've been doing "zypper patch" routinely and have been getting security updates. By chance I just typed "zypper up". It looks like my full system needs to be updated per zypper up: 1769 packages to upgrade, 4 new, 1 to remove. I'm fairly confused by that. Can anyone explain?
