Why is this cool and clever? It still only encodes 12 bits of data, it is just different to using the normal 12 bits of data.

Is this a more useful subset? I am guessing it is so, since they went to this trouble.

It can generate 4096 different slightly useful 32-bit values. For others, you may assemble them using a variety of methods.

It generates fewer than 4096 unique values, as some values map to the same thing. The most obvious being that 0 shifted any number of places produces 0, but also 0x10 shifted left 0 is the same as 0x04 shifted left 2 is the same as 0x01 shifted left 4.

Makes sense. Well... It produces less than 4096 interesting 32-bit values.
