When paused why try to fetch every 1000 ms?

In highLevelConsumer.js there is this code:

this.on('done', function (topics) {
    self.updateOffsets(topics);
    if (!self.paused) {
        setImmediate(function () {
            self.fetch();
        });
    }
    else {
        setTimeout(function () {
            self.fetch();
        }, 1000);
    }
});

The .fetch() function is as follows:

HighLevelConsumer.prototype.fetch = function () {
    if (!this.ready || this.rebalancing || this.paused) {
        return;
    }

    this.client.sendFetchRequest(this, this.topicPayloads, this.options.fetchMaxWaitMs, this.options.fetchMinBytes, this.options.maxTickMessages);
}

This means that even if the consumer is paused, it will try to fetch every 1 second:

       setTimeout(function () {
           self.fetch();
       }, 1000);

Why try if the code in .fetch() will just return?

        if (!this.ready || this.rebalancing || this.paused) {
        return;
    }

@jezzalaycock seems to have written those lines.

I think those lines can be removed.
