When to use Page.IsValid?

I'm going through my colleagues code, he has written several Page.IsValid checks but I can't find a single validation control on the pages.

Is it true that without any validation controls, the Page.IsValid will always be true? And hence, it’s practically useless checking Page.IsValid, isn't it?? please advice me with some info on this

To use Page.IsValid, first invoke Page.Validate(), which sets Page.IsValid to either true or false based on the validity of all validation server controls in the Page.Validators collection.

If you access Page.IsValid before invoking Page.Validate it may not contain a correct value.
