Question

TELL ME IF THIS DOES NOT CONTRADICT ITSELF?
iPhoto '11 or later: About the Library Upgrader
You might see this message in iPhoto: "To open your library with this version of iPhoto, it first needs to be prepared." If you do, you can use the iPhoto Library Upgrader tool to prepare your library to work with the current version of iPhoto.
The iPhoto Library Upgrader is a tool that prepares libraries from iPhoto '08 (v7.x) or earlier so that you can upgrade them with the current version of iPhoto. If your library is from iPhoto '09 (v8.x) or later, you don't need to use this tool.
THEN HOW DO I UPGRADE MY LATER VERSION??

Answer 1

Ok I will - There is No contradiction at all - Notice the CONDITIONAL STATEMENT
You might see this message in iPhoto: "To open your library with this version of iPhoto, it first needs to be prepared." If you do, you can use the iPhoto Library Upgrader tool to prepare your library to work with the current version of iPhoto.
If you do not see that conditional statement then your library will simply be upgraded with no additional software required
Exactly as the quote you posted says
The iPhoto Library Upgrader is a tool that prepares libraries from iPhoto '08 (v7.x) or earlier so that you can upgrade them with the current version of iPhoto. If your library is from iPhoto '09 (v8.x) or later, you don't need to use this tool.
Really simple - if you have iphoto '08 or earlier backup your into library and download and run the iPhoto library upgrader and then launch the new iphoto to finish the upgrade - If you have iphoto '09 or l simply backup your iphoto library and launch the new iphoto to do the upgrade
