Boies: What non-Microsoft browsers were you concerned about in January of 1996?
Gates: I don’t know what you mean “concerned.”
Boies: What is it about the word “concerned” that you don’t understand?
Gates: I’m not sure what you mean by it.
Boies: Is—

Isn't this how you are supposed to talk to lawyers? They make it their business to routinely try to force you into their own prepared lines of questioning and try to use your own words against you and make you appear to say things that you didn't really mean. This is their job.If you are on the other side of this, it is your job to prevent this use of language and make sure that they don't manage to implicate yourself in any way, by nonchalant use of words. Being vigilant about your use of specific words in specific contents, and about querying what exactly they are trying to say by each question seems like a good default approach to the problem of not giving your opponent attorney more ammunition than they should fairly have. I imagine Mr. Gates was used to mistreatment by lawyers and simply speaks their language at that point.
