It all depends on the oven. Unfortunately, the overwhelming majority of pizza reheating presets don't result in the hot, springy, gooey pizza with a crispy base that most of us are looking for. This is why we generally lean towards using the instructions above regardless of whether there's a pizza setting. With this being said, test out your pizza preset and pay close attention to how it warms various quantities and types of slices. Certain toaster ovens are surprisingly good at auto-detecting the right heat.
