PPL exam question on pressure

Please see the explanation below. Why should you look out below when flying from a high to a low pressure? I thought a lower pressure would show you are lower than you actually are so, if anything you should look out above.

I understand that flying from high to low temperature you should look out below. It's the high to low pressure that I don't get.
Thanks
