No, it's because it's a separate organization on GitHub. The chart is from GitHub's evaluation of contributions to public repos per GitHub organization. (From their GitHub Universe analysis site.) If the contributors to both the Angular and Google organizations don't overlap at all, they "win", but there's probably at least some overlap.
(Of course, if you were to do try to merge the Angular and Google org statistics then you should probably also look at all the other orgs listed at the bottom of microsoft.github.io too. I'd be curious to see someone do the BigQuery work to update this query to account for multiple known official organizations per company.)
FWIW, the Google GitHub contribution guidelines encourage you to use your personal email address to make contributions if you already have one. They cite a few reasons, but one of them is to maintain access/credit/identity/whatever after you leave.
This contribution list in this article is based on the numbers of unique contributors to all of the repositories in a GitHub Organization, not email accounts. Which is why you see Angular and Google on the list because they are separate GitHub organizations. FWIW, I don't know Microsoft's current policies but if you look at the Organization list it does seem like employees use a mixture of both personal-seeming GitHub accounts and professional-seeming accounts, presumably based on employee preference?
(I think the table is a little more obvious in context in the Github Universe site it is from.)
