what it is saying is, if your request is async: false then you should not use ajax.done(), ajax.fail() etc methods to register the callback methods, instead you need to pass the callback methods using success/error/complete options to the ajax call

correct

$.ajax({

    success: function(){
    },
    error: function(){
    },
    complete: function(){
    }
})

wrong

$.ajax({
    async: false
}).done(function(){
}).fail(function(){
}).always(function(){
})

if async: true //not specified

correct

$.ajax({
}).done(function(){
}).fail(function(){
}).always(function(){
})

or

$.ajax({
    async: false,
    success: function(){
    },
    error: function(){
    },
    complete: function(){
    }
})
