You don't know in this instance, and neither do I. Even if it is unlikely, it cannot be excluded as a possible explanation.
From my experiences, it tends to be walkers who board / alight the bus at Offerton, but it doesn't mean to say a wheelchair user would never board / alight at this location either.
