According to the article you provided, that is the first time that this has happened in Swiss history, so I don't think we can make it be the new definition of Democracy. And the re-vote was ordered by the court, so it isn't parallel to what the "sore losers" in the Brexit matter want done in the UK, anyway.
In addition, it apparently rested upon a question of transparency involving the government itself, not just that the political factions campaigning for or against the measure might not have been entirely accurate in their claims.
Yes, it isn't a new definition of democracy. Defintions of what that means vary a lot. A lot of firsts recently, this is a major event in UK history, a likely precipitating event for the break up of the UK, so not something to be seen through based on incomplete understandings.
Any third referendum is likely to be determined by parliament, not the courts in this case, following which an informed public will vote, which could go either way. 'Sore losers' rather understates the gravity of the possible post-Brexit scenarios.
Understatement of the year goes to your 'not entirely accurate' statement however. Entirely inaccurate is closer to the mark - £350bn more to spend on the NHS? Campaigns are won and lost on a handful of words. Get the right slogan, true or not, and you're more than halfway there. Never underestimate the power of an emotionally laden message to turn people's brains into creators of alternate realities.
What are some facts?
Brexit is likely to have a number of serious impacts :
On science:
Graphene inventor Andre Geim: No-deal Brexit would destroy UK science
A no-deal Brexit could lead to a catastrophe for science in the UK
(Boris visas for scientists is a wholly inadequate response to this, according to leading UK scientists)
London's primacy as an international financial hub could survive, or could go down the tubes:
Can the City survive Brexit?
A great strain on the UK's relationship with Ireland, the consequences of which could be lasting and of the most serious nature:
Most disastrous perhaps, the ultimate effect on the UKs healthcare system:
(this is very incomplete list. According to the UKs top medical professionals a no-deal Brexit will literally lead to the deaths of significant numbers of people. Of course, you can take Boris's word over our top Drs if you like -what do they know?)
What does Brexit have to offer? I can't find anything to convince me that it is anything more than a pointless waste of time and money. Those leading the Brexit campaign all stand to made large personal gains from it (
Brexit leaders prove that the campaign to leave the EU was entirely driven by self-interests )
But for anyone else? Vague assertions about sovereignty are utterly meaningless; trading one set of trading partners with all of the attached obligations for another has nothing whatsoever to do with sovereignty. The Queen, who I swore allegience to, is all for the EU. All of the other characters involved have nothing to add to the UKs sovereignty. If Farage and the like are so concerned with the idea, why have they secured themselves EU citizenships? Why has Dyson moved his operations to Singapore? The Brexiteers ability to override facts with some basic jingosim in the minds of so many is a predictable but sad reality.
US misunderstandings of the whole scenario are typified by Pence's crass and poorly informed notions, as can be seen in the responses of the Irish press:
