The footnote reads, "That is, xor(x, y) is true if x is true, or y is true, but not both. This is how we usually use 'or' In English. 'Both' is not usually an acceptable answer to the question 'would you like ice cream or cake?'."
This is incorrect. The inclusive or is used quite frequently, as is the exclusive or. The example given is not actually a terribly good example of the exclusive or: there are many times when someone might want ice cream with their cake!
Some examples of the inclusive or:
Applicants must have experience in teaching or tutoring.
You can call or text me.
Students can major in mathematics or physics.
If the flood rises or someone gets hurt, call 911.
Context is essential to understanding which "or" is meant.
