WHY did Yamaha name the following Tyros styles as 6-8?

Soul6-8
6-8SlowRock1
6-8SlowRock2
6-8ModernBallad
6-8Orchestral

These styles appear (to me) to be 4/4 with a 12/8 (triplet) feel, not 6/8.

This led me to investigating the "how to" of figuring out the difference between 3/4, 6/8, and 12/8 time signature feels. I found the following website link (including MP3 samples) both educational & interesting:
Difference Between Time Signatures: 3/4, 6/8, 12/8

Ok folks, I'm interested in hearing from others here regarding the above Yamaha Styles. Do you feel they're correctly labeled as 6/8?
