I mean, it's an accurate statement. It's just also true that people usually don't want to be deposed even if they have nothing to hide. The "when they have something to hide" part is just superfluous.

It's not just superfluous, it changes the meaning of the statement. It's like saying "I like women when they aren't driving". You can't follow that up with, "oh, but I also like them when they are driving, so it's okay to say that".
