Currently it is just something I've read, but there's good reason to believe this is true. I have caught a few snails where the orientation of the coil of the shell is only on one side (I believe it's clockwise). But since they're too small, I can't feed them to the snakes yet. They also have the disadvantage of being rather slow growing.
Most of the snails that I've fed them to, are what I believe to be the Brown Garden Snail (Helix aspersa). They will only eat individuals that are approximately between 1 cm and 2 cm in diameter.
For slugs, they will eat individuals that are approximately between 2 cm to 4 cm in length when fully extended. I cannot identify the slugs I feed them to down to species, but I believe the genus is Deroceras.

I don't know how old they are. These are to my knowledge quite possibly wild caught specimens (I could be wrong). The seller did not give me an age or date of birth, so my assumption leans towards the fact that they are wild caught specimens.
The seller didn't feel comfortable sexing them in the manner in which you speak of, because of how slim these animals are.
I do not feel comfortable either, considering that I'm not a very experienced snake keeper, and the fact that these snakes are not only very slim, but very nervous creatures. They do not stay very still when handled. They always want to slither away.
To give you an idea of how slim these snakes are - where the vent is, it's only about 5 mm wide. I believe the widest part of the snake is only about 1 cm wide.
Below are new photos of one of them eating. The other snake was feeding as well, but it was in the back of the tank and my camera lens cannot get a good focus on it. In both instances, the snail's shell was pushed to the right side of the snake's mouth. You can look at the pics and judge for yourself whether there is truth in the right handedness of Pareas carinatus.
