I don't know. I pop my ears the same way if I perceive negative pressure or if I am about to swallow. That's because if I swallow with my ears like that, there will be a loud 'plonk' sound in one or both ears, and a dramatic change in pressure in my inner ears.
Both swallowing and intentional popping do seem to cause middle or inner ear complaints for me. I would try to avoid popping your ears intentionally under most circumstances, except when it's necessary (on a plane, altitude change, diving).
