Its compulsory to provide full details when you take it out. They often provide a summary as well.
If I go into my AVIVA account I can see the policy T&Cs and summary and renewal invite etc for every policy from when I moved the to them (about 5 years ago)
I suspect Tesco have changed the wording, this happens a lot, to clarify or to take account of rulings etc, but I would highly doubt there wasn't something similar in there all along.
Black box policies offer a (normally) significant premium reduction in payment for offering up more of your relevant details to allow the insurance company to assess risk, which is fine if you only marginally exceed, but if one of your actions takes them outside what they accept to be risk they are willing to bear then your going to have issues.
A normal policy would be no different if they knew you regularly speeded your more of a risk. They dont however get to know about this until you pick up points, which is a very imperfect way of loading the premium for those causing more risk, ut its the best they had available until black boxes.
