Have you tried validating the code that is written with H1 in the breadcrumbs? I'm not suggesting validation is scripture but it might give you an idea of whether is acceptable by standards or not and that might suggest what certain search engines might "think".
On the other hand, it might be a loophole. How is your competitor doing after they added that? Did you see a big rise in their traffic/SERPs or nothing at all? Also, have you used the structured markup tool to see if it recognizes the code? It probably would.

Bad in the old days of the net some used the h tags for "style" purposes because of the default font sizes. These days most folks use the h tags correctly, for document structure. That does not seem to be the case here, and I am confused why anyone wouuld think a h tag in navigation would make a difference.
There should be only one h1 tag per page, or section, of any document, and a breadcrumb navigation, by definition, is not part of a document, merely a path to a page.
