Galvanic action can occur when improper fasteners are used in a building facade. Image a stainless steel building component (fairly cathodic) is fastened in place using galvanized (zinc-coated; highly anodic) metal fasteners. The galvanized fasteners would corrode as the ions in the fasteners moved toward the stainless steel. Eventually, the corroded fasteners would fail - leading to damage and possible injury.

Pretty sure it’s intended or such a small issue it’s not really relevant
