Wondered that myself.
Plus there is "Cue & Case Gallery" which I understand why this one is different. This one is for just showing off cues and cases for all to enjoy, while the other is more for information, good or bad, about the product. Occasionally someone gets them confused, but mostly they are correct with the gallery for show and the reviews for informing others about a product or brand.
Combining the two reviews would be less confusing, or having one for general cue reviews and changing the other to just shaft review might work as well.
