I've wondered this ever since it signed on. Absolutely pointless. Destroys any chance of WVLK-FM ever being received in that area again. It actually had a decent signal the entire length of the Bluegrass Parkway before that stupid translator signed on.
On a related note, there's also a translator for 94.3 WULF on 104.5, which is also pointless. WULF provides a nice 65 dBu signal in Etown where the translator is located. There is no way people are having any trouble receiving 94.3 clearly in Etown. WLKT used to have a decent signal in and around Bardstown before the WULF translator. Those days are long gone.
