It isn't, not really. The article describes the NV-A (New Flemish Alliance) as a center right party that's somewhat courting far-right voters. In reality, they have a very strong far-right contingent and the party as a whole is becoming much more radical. They're just very savvy with their wording and maintaining plausible deniability.
Recently, a far-right youth group Schild en Vrienden (somewhat similar to the Proud Boys in the US) was made public. Most of these guys were talking about voting NV-A, protected a talk by one the most popular NV-A members, and NV-A kept mostly silent about the whole affair.
