Because when you talk to a person and you are facing each other, they look the opposite of you (your left is their right). But when you look at a mirror, it is basically like the mirrortook a picture of you and turned it around so it's backwrds and you can see it... It's like you were made to talk to yourself but your second self was made to look (to you) like he was doing the exact same thing as you, but in order to do that, his left hand would have to be on the same side as your left hand and such, and so it's technically a backwards version of the normal person talking to you in that respect and since up and down are always the same for both people anyway, it doesn't need to switch. That's the best I can explain with time I have. It doesn't have any effect on up down.

A mirror in fact does not invert left-right OR top-down. What it actually inverts is front-back.
It is only after we perform a horizontal rotation in our minds, in order to align the person we see with our own orientation, that begin to think right and left have been reversed.
