Where the article explains it
When any of the coefficients is nonzero, the vacuum of the a -decomposition is a many-particle state of the -decomposition, and vice versa: “how many particles are present” is a question whose answer depends on which set of modes was declared fundamental, not on the field configuration by itself.
