Certainly, cloning techniques are more likely to preserve plants of the same genotype, which will, then be more likely to, in similar environmental conditions, display a similar phenotype.
When using the "floating in water" technique, I've noticed absolutely no difference in propagating the different types of this species from leaf cuttings and even chopped flower stalks and buds. I've even had a few that were self-pollinating and self-fertile that even became a bit weedy like Drosera capensis can. At least Drosera binata seedlings/plants, like Drosera capensis can easily be discerned, from most all other Drosera, keeping them from creating identification issues.
Lack of "points", most likely environmental issues. Full sunlight, or near equivalent, moderate humidity - 60% or better, good water and lots of it.
