Offset default value

[Jonathan Sondow]

%O = Offset a, b :

*    a is subscript of first term
*    b gives position of first entry greater than or equal to 2 in magnitude
(or 1 if no such entry exists)

But why is 1 the default value of b? Wouldn't 0 or even -1 be better? After
all, the value b = 1 can appear in the usual, non-default case.
