I went through this with my maltese, Casper; though the vet made it sound like no big deal.
This was years ago; he really didn't give a lot of details about the neuter surgery - just that it would be slightly more expensive. Anyway, he went in and got the other testicle when he neutered him and Casper was fine.
Hopefully since your pup is so young; the testicle will descend. If not - they will want to go in and get it for the reasons you were given.
