An interesting find with stats.

Bits are read from right to left because that's the way they're written via ASM commands. Bit 0 is the rightmost bit, bit 7 is the leftmost bit. This is a convention because of how digit‐based number representations work: the binary number %01101010 is equal to
0 × 2⁷ + 1 × 2⁶ + 1 × 2⁵ + 0 × 2⁴ + 1 × 2³ + 0 × 2² + 1 × 2¹ + 0 × 2⁰

It's the same way with decimal numbers the farthest right column is the ones place, to the left of that is the tens place, and so on.
