[governance] The decentralization of the DNS system

It is simply a tool to query DNS and get specific / verbose details in your DNS query.
In essence, that query below shows you the path a DNS query for the MX record of “theglobaljournal.com <http://theglobaljournal.com/>” (that is, what mail servers handle mail for theglobaljournal.com <http://theglobaljournal.com/>) took, all the way from the root servers, to the DNS server(s) for theglobaljournal.com <http://theglobaljournal.com/> - managed by Jean Christophe’s provider gandi.net - which then responds with details of the mail servers on which his email is hosted.
That path flows down from the root servers - and guarantees that whoever, or whichever dns server anywhere in the world, makes that query, will end up with that answer.
With an “alternate root” setup, there could very well be one set of roots claiming that Jean-Christophe’s email resides on, say, a mail server at a university in India, rather than on his provider Gandi.net <http://gandi.net/> in France. To use a sort of correct analogy, that would be like if you searched a telephone directory for his address and phone number, and found two different entries for those under his name. [of course assuming he is the only jean-christophe nothias in his city - like there is only one domain theglobaljournal.com <http://theglobaljournal.com/>]
I hope that makes McTim’s reply clearer.
