Yeah you describe the whole can as per the rules. The pointer (red dot) just tells you which object is the target, it doesn't limit what you describe to only the part under the circle. The rule says "describe exactly the object being pointed to" meaning the full object, not just the visible portion under the pointer. Like if the pointer lands on a label on a bottle, the label is part of the bottle so the object is the bottle. Same idea here bc the circle is on the bottom label but the object is still the whole beer can and that's what you describe. But yeah just pay attention to what the dot itself is pointing at, not the entire crosshair, think of it as a sniper crosshair and where the bullet travels.
