As can be hinted by the name of the method, there are two types of latent traits. : (1) matching latent traits that are designed to quantify the strength of the interaction between two species and (2) centrality latent traits, which quantify the number of relations a species has with other species. Mathematically, these latent traits (both matching and centrality) are all orthonormal with each other, within and outside of their category.
When deciding on the dimension of the lantent traits, aside from technical issues (i.e. the number of parameters to estimate and the size of the data) it is important to also consider what is gained (or loss) from increasing (or decreasing) the dimension of the latent traits. The default was set to 2 because it is often of interest to study latent traits in pairs in an ordination-type graphic.
