How would the mouse behave in a mirrored environment?

Sorry if it sounds confusing, but this is not a biology inquiry. I'm planning to switch to Linux, but I have a few questions need answered. If a single monitor is mirrored like described in this link , then will we see the pointer onscreen move similarly to, or contrarily to our physical mouse-hand movement? In case it is reversed, is there any way to make the mouse move like in normal setups while keeping the screen mirrored?
