My theory is that all semblances are like the Schnee's in that they can have multiple abilities that are at least loosely connected to each other, or in the case of non-hereditary semblances, the user.

The only reasons the Schnee's are so skilled is because they have the capability of passing knowledge down about their semblance. But with sufficient training, others can unlock far more powerful and different abilities for their semblance.

For Ruby, one explanation is that she can turn into rose petals. This allows her to literally split herself into three and also reach far greater speeds due to the form she takes.
