Why would you think that's strange? That's the normal difference you'd get between
black and white. While John and Brian are pointing their light sensor at the
cube/square to check for one of three states (black cube/white cube/no cube) you're
using a mechanical sensor to feel cube, and a light sensor to look at the state of
the mechanical sensor.
It's a good strategy (and a bit harder to implement) and you only have to
distinguish between two values.
It is kind of strange that after hearing how they're doing it, you'd compare your
results. :)
