Luxembourgish, just like Dutch, Frisian, and German, is part of the Continental West Germanic Dialect Continuum. It is perfectly mutually intellegible with other Moselle Franconian dialects in the surrounding areas.
It is also mutually intellegible to a certain degree with Standard German. Being a native speaker of that language, I personally find it easier to understand than, say, Lower Alemannic, which is spoken in the southern tip of Germany.
Luxembourgish is not a different language from Standard German in terms of abstand - linguistic differences, that is - but in terms of ausbau (language policy/expansion/development). It is the language of a different state, of a different population group, of a different language planning institution. It is a not very different language of a very different country.
However, due to historic reasons, German still is the main language of written media such as newspapers in Luxembourg. That's why the article is in Standard German.
