Why bother?

Perhaps this is because the processor itself works that way.

Also, the multi-byte registers are set up that way:

$04 ($24) ADCL ADC Data Register Low Byte
$05 ($25) ADCH ADC Data Register High Byte

R26 0x1A X-register Low Byte
R27 0x1B X-register High Byte 
R28 0x1C Y-register Low Byte 
R29 0x1D Y-register High Byte 
R30 0x1E Z-register Low Byte 
R31 0x1F Z-register High Byte
