INF for FS MiniFilter

Hi!
I happened to look all the INFs provided in WinDDK for MiniFilters.
In all the INFs the Class and ClassGUID was same. The only thing that differs is the LoadOrderGroup.
In Scanner sample it is “FSFilter Content Screener”
In passthrough sample it is “FSFilter Activity Monitor”
In SwapBuffer sample it is “FSFilter Encryption”

I wanted to ask whether Class and ClassGUID should also be different??

Thanks!

How far can this affect the behaviour of my filter?
