Yes, legally it is perfectly clear. Just not the why. Is there any other language that has taken a similar approach? Has this been discussed in relation to Hare somewhere apart from the brief chunk of text that I linked? I am perfectly accepting that I may be in error here in terms of how I view licensing, but it bothers me that I can not build a mental model of the intentions of the authors.
