No, no, no.  You're not hearing what you're being told.

You use "sudo" for _command line_ apps, like apt-get/aptitude.

You use "kdesudo" for GUI apps, like kate.  

You can switch around but kdesudo _has_ to have a desktop to display it's 
popup prompt, and sudo can have trouble attaching to the users display.
