You know, you're probably fine if you always assume there's only one body tag. That said, I've seen this and worse when looking at the output of highly-paid web dev departments at large companies. One site we recently saw had five opening html tags, head sections, and body tags. All the head sections were different, and none were closed, including roughly half the content tags we saw. It's a testament to the "be loose in what you accept" mantra of the web, and to the browser devs themselves, that this monstrosity rendered properly. I'm not saying "enterprise" developers are bad by definition, but the enterprise sure is large enough for the bad ones to sneak by.
