That is correct. This is because the HTML5 <figure> element states that the
caption is optional.
http://www.w3.org/TR/html5/grouping-content.html#the-figure-element

Here is the text:

The figure element represents some flow content, optionally with a caption,
that is self-contained (like a complete sentence) and is typically
referenced as a single unit from the main flow of the document.

We can require this but there is nothing requiring the HTML5 element to
have a name. I am trying to ensure that this fits HTML5 as well for default
native host language semantics. Although,  I would like to hear from Steve.

An additional thought:
It says that the figure element should be referenced from the document
text, but providing an accessible name for the figure is optional.
In order to ensure usefulness and the ability of the assistive
technology user to locate the figure, it needs to have an accessible
name (consistent with how it is referenced in text).
