What we are seeing here are simply "archetypes". We have the archetypes associated with function position, but the types and temperaments themselves are also archetypes. They have been known for millennia, and they have been named after astrological signs, after body humors (Hippocrates, Galen), after "walks of life" or character styles (Plato, Keirsey), or with all new names (like Keirsey's individual type names) or break personality down into its factors and label them by the abbreviations.
So all that Aries profile is, is a description of the same archetype known as a Choleric or Sanguine-Choleric blend, that is embodied in an ENTx type.
The problem with astrology is that it builds a personality system off of the stars, and everyone born under that sign (at that same time of the year) obviously does not have that same personality. The same with personality being a result of the humors; but at least that theory eventually dissociated the personality types from the humors. (And is now looking at something directly specific to the individual, which is the brain).
