I guess I'm of two minds on it. On the one hand, yes, it's a lighter boil, no question about it. On the other hand, I've done enough reading on this topic since picking up this hobby to know what sorts of side effects a lighter boil can create, and I'm still not entirely convinced that those side effects are legitimate concerns anyone could detect in a batch of homebrew.
The most common things are DMS, lack of hop isomerization, and even beer clarity.
(source*) The DMS argument is the flimsiest of the bunch IMO. Clarity can be countered with a fining agent in the boil or later in the fermenter. The hop isomerization argument is the one which seems to have solid science supporting it, and is a very fair counter to the opinion that light boils have no side effects, but I haven't come across any research which seems to communicate the sort of utilization hit one would take by failing to reach a rolling boil for the duration, or again, if any of us could do a blind A/B test and tell which pint was borne of a rolling boil vs a lighter boil.
If the product cannot boil high gravity beer as it claims throughout the promotional material, it's an $800 HLT and they're going to be issuing refunds to a bunch of early adopters due to false advertising. Basically the worst thing a company can do when trying to get a foothold into a huge market.
* the article I linked is already showing its age quite a bit (HSA, not desiring overly bitter hop profiles, etc) but the research is thorough and a great jumping-off point in the conversation.
! But still want to answer your questions about the boil.
