  That is not quite correct.

  An overall anisotropic B term is applied equally to all atoms in the 
  structure.  If the atoms are otherwise described isotropically, this
  will turn them all into identically shaped ellipsoids instead.

  A single TLS group, on the other hand, describes a position-dependent
  anisotropic model.  Every atom in the structure will get a _different_
  ellipsoidal shape, where the shape is a function of its x/y/z coords.
