Why wouldn’t the brick have been repaired when foundation issue was corrected

I am in the inspection period of buying a house. The only issue that concerns me is this stair step crack. I have foundation repair paperwork from the seller. It’s a lifetime warranty and is transferable. The paperwork shows the foundation repair was done but I’m wondering why the brick wasn’t repaired. Does this make it cosmetic damage? I plan on contacting the foundation company but I wanted some opinions from somebody who knows more about these things.
