This sort of suggests that URLs that are short and keyword-informative might be less likely to receive the breadcrumb hierarchy treatment

A site I am working on has the following URL:
example.com/widgets/blue-widgets/fluffy-blue-widget

G' displays this as:
Fluffy Blue Widget - example.com
-->snippet<--
example.com > widgets > blue-widgets

the URL/keyword information is exactly the same as the hierarchy treatment.
