Unless he/she has my luck which is the really nice nems don't split only the common cheap ones do for meYou also can look at it this way... 6 months you will have two, 1 year you will have 4-8.
Just watched a RB video with Remy. He did a profile on a guys system and he had a tank with over 200! He also sells 4-5 a week!
I had 3 rose bubble tip that eventually reached 50 and one really nice red bubble that I've had for 2 years and still only have one.
For me in think it's tank stability and maturity. A few years ago my nems were splitting like mad but I haven't had a split in well over a year but tank has been super stable and is going on 8 years old
