No, there is nothing special about those named points.

There are no strict definitions for semi- vs pseudoLM. In SlicerMorph we use term semiLMs for designated geometrically samples landmarks that are bounded by manually placed anatomical landmarks (e.g., those are generated by CreateSemiLMPatches module). PseudoLMs have no such constraints.
