My comment was a follow-up to 'how do you define same area' though. You may think they're in the same area, but if you eventually find them both and one was 20 yards longer and 20 yards further right, then technically they are not in the same area perhaps? Since it isn't defined.It would be pretty clear they'd be expected to be in the same area, if you searched the same area for both balls.
Whereas if you sliced the first one right, and carved the provisional left, then it is fair to say they are in different areas. Or if one ball was duffed down the right 100 yards, while the next ball was hit down the right 150/200 yards, they'd be expected to be in different areas.
I think beyond what the rule states, it is best to rely on the golfers integrity to understand when then are looking in the same area for both balls. If the rules went further and stated the expected area is a 10m by 10m grid, and the overlap in search area must be no more than 2m, then it would start to become ridiculous
