i'd like to see an example that actually makes sense. the only one i can come up with is that i might not want to hire people who have more experience with windows than with linux. but even in that example people with less windows experience would be ok.
if you have a realistic use case please describe it.
Yeah, if you're hiring for a senior-level role, 10 years of experience with Linux is 10 years of experience with Linux, even if the person also has experience (perhaps even more than 10 years) with Windows.

Why? You are clearly missing the point and lack imagination. Another example won't satisfy you the way you think it will.
