The patent holders of the Dermaroller disagree with this:
https://http://www.dermaroller.de/en/faqs/68-how-often-can-the-dermaroller-procedure-be-repeated They say that a minimum of six weeks interval is required. It is not clear what needle size they're talking about (The longest needle length roller they manufacture is 1.5 mm and the longest needle length they sell to private individuals is 0.2 mm), but they manufacture a wide variety of sizes and their smallest permissible interval to roll with long needles is 6 weeks. So there is no concensus amongst experts.
I read the PDF you linked to, and there the recommended interval with a 1 mm roller is "minimum one week and maximum one month". Firstly, the "maximum one month" seems arbitrarily chosen and is certainly not based on any objective scientific criterium because evidence exists that skin remodeling takes longer than that.
Also, the optimum treatment pause depends on such factors as the patient's age and the skin thickness rolled, as well as how vigorously is rolled. We therefore read the available professional literature and expert opinions on this subject and came with a general recommendation of two weeks pause for a 1 mm roller. Incidentally, this ties in nicely with the PDF concerning a 1 mm roller quoted by you: "Micro-needling can be undertaken at an interval between one week and a maximum of one month".
The most beneficial for skin regeneration is the longest pause. The riskiest is the shorter pause.
Nobody knows yet what the best interval is, because these studies take a long time and many patients and additional factors are at play as well.
Last but not least - professionals such as plastic surgeons have a commercial interest: They need to "bind" the customer to them. If they tell a customer to come back six weeks later (because that would be the best for their skin in the long run), the customer would think: "This doctor is too slow - I'll find one that gives me faster results". I am sceptical of any advice in a hyper-commercial advertising folder that is not backed up by scientific arguments, regardless how well-known its author is.
In that same PDF ad they mention 3 mm needling as an option and their method as an alternative. But the patent holders of the Dermaroller say on their site that 3 mm rolling is total nonsense, that those needles are much too long. Again, the choice for 3 mm needles may just be a commercial one: The customer will think, when the doctor uses 1.5 mm needles: "I can do that at home twenty five times times cheaper". But when the patient gets a bloody face under strong anesthesia, she thinks: "Wow - that must be the most effective treatment possible".
