Sentence in 6.11.7 doesn't seem right

[Zhang-Junzhi]

What is the issue with the HTML Standard?

The spec in 6.11.7 says:

An element with a draggable attribute should also have a title attribute that names the element for the purpose of non-visual interactions.

I don't understand the sentence. Why is a title attribute necessary if I set draggable to false. For example,
<img alt="..." draggable="false" src="...">
Why is a title attribute is needed for the <img> element?

I think the original intent of the spec was to say "an element whose draggable attribute is true".
