What's the use of using altimeter when barometer shows altitude too?

Hey you guys (and girls?),

I've just purchased a Suunto Core black/yellow for my coming trips to the Alps. I happen to absolutely love it.

Just find it quite difficult to understand the difference between baro and alti mode. The manual says that:

- barometer uses absolute air pressure + altitude reference
- altimeter uses absolute air pressurre + sea level pressure reference

However, setting the altitude reference does not only change the barometer readings, but also a changed altimeter reading. Moreover, changing sea level pressure reference results in a changed altitude, but also in changed barometer readings. What am I missing here? what don't I understand? Can somebody help me with understanding this?

Last question: the barometer also shows altitude measurement. What is the use of using the altimeter then when climbing?

Don't want to come across like a complete moron, but I just don't get it. Thank you for your help!
