Under at least two reasonable definitions of "cluster", all of the values that are 1 are in one cluster and all of the values that are 0 are in another cluster. The most obvious "reasonable definition" there involves value, but it also happens that if you use 8-connectivity then every 1 value is "connected" to every other 1 value through a chain.
My speculation is that what you want is bwlabel() with 4 connectivity.
