You are right.

Because a string, like a zero, equals false, when |-ing.

So if you want only NaN to default to 1, you are in trouble anyway:

x='3'
y=x|1
alert(y); // returns 3, correct

x='aString'
y=x|1
alert(y); // returns 1, correct

x='0'
y=x|1
alert(y); // returns 1,
          //"should" return 0, x being convertable to a number.

Not much of a zero tolerance!
