Well, if you take off the intel x86 blinders, word has historically
meant the normal interger size of the CPU, which would be
4 bytes for 386s and newer.   Every other 32 bit
architecture I've used defines words to be 32 bits long, so anyone
with a non-x86 background would probably use word in that 
manner.  Nothing wrong with it, it just looks weird to PC 
only people.
