Bit Masking and Its Legacy

I've been doing some digging around the semantics of the Registry and bit masking inevitably came up. My question is why the bit masks go from x1 x2 x4 x8 to x10 x20 x40 x80? It seems somewhat reasonable if the bundled bits are configurations significant only in fours but it causes the ultimate mask to have multiple potential causes(aka, x43 could be 01000011 or 00111101).
