Answer 1

Because you inserted the FB.getLoginStatus, which calls your login function, in window.fbAsyncInit on every page's loads.
You should fire FB.getLoginStatus only though a button, with an onclick trigger.
Here is a little example: http://facebook.stackoverflow.com/a/15720747/2212966

Answer 2

I have mine wrapped with a jquery button click event handler. Here is a snippet from my code:
window.fbAsyncInit = function() {
FB.init({
appId : 'my-app-id',//use your facebook appId in here
status : false,
cookie : true,
xfbml : true,
version : 'v2.2'
});
jQuery('#signUpWithFacebookButtonId').click(function(){
FB.login(function(response) {
if (response.status === 'connected') {
console.log('Logged into your app and Facebook.');
} else if (response.status === 'not_authorized') {
console.log('The person is logged into Facebook, but not your app.');
} else {
console.log('The person is not logged into Facebook, so we are not sure if they are logged into this app or not.');
}
}, {scope: 'public_profile, email'});
});
};//end window.fbAsyncInit function
