I had a friend lend hers to me when I was a kid, and I did in fact try it in a cassette player! I even tried to make my own cassette, but I soon realized that I couldn't because... All 4 tracks had to be recorded in the same direction.
2-XL used the left and right stereo tracks of each "side" of the tape to store four total synchronized audio tracks, but all in the same direction of play. If you listened to "side A" on a normal cassette player, you'd hear two tracks: one on the left and one on the right. If you listened to "side B" you'd hear the other two tracks, but played backwards.
