AddBoolOr and AddImplication in cp_sat solver

Hi I have difficulty understand the following code, can anyone help to explain? Thanks in advance!

model.AddBoolOr(x, y.Not(), b)
model.AddImplication(b, x)
model.AddImplication(b, y)

Solution

It is most likely wrong. It should be x.Not() in the AddBoolOr().

It encodes b <=> x && y.
