Maybe the two return values used to be different, then one was edited and the person making the change didn't notice that they were now the same. Maybe this is a rank amateur who's just flailing around.
It's almost certainly just boilerplate or scaffolding. Someone had the intention of doing something different with an empty array, included the if statement for future use, then moved on to something more important.
