Only now do I begin to see the point you were trying to make.  You chose
that specific example because the Morning Star and the Evening Star happen
to be the same celestial body -- the same object.

However, in grammatical terms, that is absolutely irrelevant.  For example,
"The car and the patent are white rabbits" is, grammatically speaking, 100%
correct.  Grammatically correct sentences do not have to be logically
consistent.

Here's a counter example:
   The Pope and the Head of the Catholic Church are the same person.

I don't think any moderately proficient English speaker would have trouble
parsing that.

By the way, G.H.W. Bush was president from 1988 to 1992.  The President
today is G.W. Bush.  The current president doesn't have an "H".  There has
to be a pun about "getting the H out of there", but I'll leave that to the
reader.

Well, *I* use it.  ;)

I'm inclined to disagree, but in contexts where it is important, I always
try to say "a and b are bound to the same object".
