xinput query-state output confusions

   ↳ GTech MI wireless mouse Consumer Control  id=20   [slave  keyboard (3)]

The result of

xinput query-state 6

however is an array of 247 keys. How does a power-button have 247 keys?
Do these even correspond to my actual power-buttons? I tried to disable them through:

xinput disable 6

but the power buttons still work
