just be aware that corporations do change policies over time, including how to name authors in contributions.
Which is to say, I would not be willing to assert that an employee of company X would always be required to follow the same rules about copyright and author naming. Going back and retroactively changing everything is usually Not An Option/A Bad Idea. Hence, it is possible that a name might change over time, from the same person, at the same company.
I'm not saying that is happening in this case. But I think you're being a little unrealistic.
