It's just a convenience, so don't worry about it if you don't want to make a bootable USB image. I do recommend that you make a bootable clone backup of your current system before installing Mountain Lion or any new operating system. With current fast disk drives, even if you have a mostly full hard drive, it's worth taking the few hours for the process to run just to have the security of a fully working system. You can use either SuperDuper! in the free, trial version, which completely supports making a bootable clone -- just not the other incremental functions, or you can use Carbon Copy Cloner, which also has a free 30-day trial, I think, and which will let you use all functions within that period.
If there are any incompatibilities with the upgrade, you can immediately connect your bootable clone to your Mac, and boot up while holding down the Option key. Wait for 15 seconds, press the left arrow key once, and then press "Return", and you'll boot into your old, familiar operating system. I keep bootable clones of every OS I use. It doesn't have to be exactly up to date, but it's a great feeling to know there is an instant recovery for most disasters. This is different from TimeMachine backups, because you can use them, as is, immediately. HTH.
