Who said anything about copying?
I believe it is checking whether the range fromIndex, fromIndex+1, ...,
toIndex-1 -- i.e., a range given as the first index and one past the
last index, not an uncommon practice -- is within the array, in which
case it has no bugs. (toIndex may legally equal the length of the array
when the range extends to the last element, and requiring the range to
be specified "the right way around" is not especially perverse.)
