No, that's just the weather correction. You don't really need to worry about the altitude since it uses the absolute barometer reading.
The altitude will just give you the general air pressure at 2100 feet for example. It's based on the SAE baseline ideal variables like 60 degrees with no humidity air pressure at sea level etc. Of course there are many other factors at play with low and high pressure fronts varying humidity and wind etc. So it's more accurate to take an actual barometer reading than to rely on what they think the air pressure should be at 2100 feet at ideal circumstances.
I hope that made sense, I was typing kinda fast.
