I absolutely love the design...

P.s. I know there is a little arrow that does an animated automatic scroll upwards but for me needing such a thing is a clear indication of a flawed design. Instead of fixing the symptom you should fix the root cause..
Displaying the menu and home icon on screen at all times, comes with trade offs such as:
- less screen space available for other items
- implementation difficulties with floating fixed icons
- distraction from content
- overlap with on-page elements
And that's just what I can think of at 6am, pre-coffee. I would imagine the actual team has dozens of reasons behind their choice.
To choose not to do so is design choice, taking into account the entire situation.
Now you as a single particular end-user may not agree with their choice, but that's not a universal "flaw", but the essence with compromise in general---someone will lose out and be unhappy.
Making the navigation menu not easily accessible at all times, where I count having to scroll up 3 pages not easily accessible, is a design flaw to me. Note that my first comment also mentioned to _me_, but that may have been missed before the first coffee went in :).
