Technically there is a difference. A “world record” qualifies on the basis of standardized conditions, whereas a “world’s best” does not control for those variables.
Well technically there's a set of WA "world best" distances and 50 miles isn't one of them. So it wasn't even a world best when he set it.
However, it looks like IAU just made 50 miles a world record distance, effective 3 days ago.
