Yes, the bot made broken pull requests to some 35 repos before all the issues were ironed out. As a maintainer of those repos, I would be annoyed at these 'corrections'.
For my part, I manually corrected all of them and apologized to the maintainers for any inconvenience. The corrected pull requests were accepted, and the bot went on to submit correct fixes to several hundred other repos.
There's always the opportunity for bugs, but once they were ironed out it was able to happily submit correct fixes for hundreds more. I think that makes the idea worth something.
