Isn't "adding" the same as "moving closer" ?

E.g. the vector for "bank" is mid-way between the geographical and financial meaning, "bank + money" is closer while "bank + river" if further away.

It depends on the values of the vectors. (4, 4) + (3, 3) results in a new vector (7, 7) which is further away from both contributing vectors than either one was to each other originally. Additionally, negative coefficients are a thing.
