Power Adapter/ cord wattage

“Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple notebook, you can use an adapter of a higher wattage without issue.”

Magsafe Adapter 1 or 2?

I don't understand that paragraph from Apple's site. I never have, and I never will. Didn't they just contradict themselves?
