N:M Check associations is not working as mentioned in the docs

What are you doing?

// code here
From Sequelize docs
// check if all associated objects are as expected:
// let's assume we have already a project and two users
project.setUsers([user1, user2]).then(() => {
  return project.hasUsers([user1]);
}).then(result => {
  // result would be false
  return project.hasUsers([user1, user2]);
}).then(result => {
  // result would be true
})

What do you expect to happen?

It must work as documented

What is actually happening?

Not working as documented

// Example Scenario
Returns true instead of false for this scenario
If project as 2 users user1, user2
project.hasUsers([user1]);  // => returns true instead of false
