According to our documentation, the braille verbosity setting:

"determines the amount of information that will be brailled in certain situations. For example, if it is set to verbose, keyboard shortcut and role name information is displayed. This information is not displayed in brief mode."

We seem to always present the shortcuts. And the only time I found that we changed behaviors with respect to rolenames was with page tabs. To make matters worse, not only do we have this bug, I cannot "fix" the documentation by finding a different example of braille verbosity because a quick grep through the code suggests this is the *only* thing we're doing with braille verbosity. :-/
