I think that phrase was just mostly meant for the average reader of the article.

If you read the study they link, it explains the immune boosting/modulating functions of the honey.

Example: Furthermore, the ability of honey to reduce ‘reactive intermediates release’[23] may well limit tissue damage by activated macrophages during wound healing. Thus, the immunomodulatory property of honey is relevant to wound repair.

I've seen this stuff work for wound repair first hand, and I've read enough first hand accounts of people successfully treating gut-related diseases with the help of this stuff.. so maybe don't dismiss it just yet, but if this gets very popular, I don't think NZ will be able to keep up.. the prices on the stuff are already a bit much for any average shopper.
