Econ - expected inflation and shift in AD and AS

CFA Level I

Hi, during one reading, I read the following in the section that talks about “when inflation is not anticipated”: - aggregate demand moves to the right (rises) in line with actual inflation - aggregate supply moves to the left (falls) in line with expected inflation Can someone helps me understand the above ? why in one case it’s “actual” and the other case it’s “expected” ? Tks
