On trying to catch up with this thread I don't think I saw what
I would have considered the most likely reason for the term
"logical".

I assumed the word "logical" refers to Boolean logical values
(true and false, usually represented as 1 and 0) and hence to a
bit string.  So logical comparisons simply treat the operand as
a bit string.
