Bltizen, the skepticism comes for a reason. You would not believe the number of people who have been wrong about this in the past, both here and elsewhere, when they missed a simple checkbox, and they swear up-and-down that they are right, but then they use the same method again and realize they missed it.
That said, there are plenty of people who have reported this. It is almost certainly a bug. Even if it was a forced bundle install, it would at least check to see if Chrome was installed first, rather than installing Chrome over the top of an existing install.
