I am curious about this sentence: why is it "exactly what we want" ?

Indeed, the variable assignment was not double quoted before, and now
it becomes double quoted:
is what I have in the resulting /etc/profile.
So does "exactly what we want" means "preserves the existing behavior"
or means "is better than the existing behavior" for some reason ?
