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.
