Yes, interesting comparison, indeed.
But Latin is
not an agglutinative language. It doesn't function this way.
The resemblances come, I think, from the fact that Latin ang Magyar are both languages with declensions, though they don't belong to the same linguistic branch. But it doesn't necessarily mean that there are relations between them.
Anyway, in linguistics, syntax is not considered a pertinent criterium to distinguish or associate languages, for they quite often borrow one to the other, especially when they are geographically close, as Latin and Magyar. The pertinent criteria are phonetics, morphology and lexicon. And the author of the site almost only compares both syntaxes.
