appear to be 'tipping the scales' in favor of 'facilitating
antibodies', which make the virus more virulent from the "neutralizing antibodies" which help the immune system to fight it.
In the paragraph above the one you quoted they say:
"Current Covid-19 vaccines (either mRNA or viral vectors) are based on the original Wuhan spike sequence. Inasmuch as neutralizing antibodies overwhelm facilitating antibodies, ADE is not a concern. However, the emergence of SARS-CoV-2 variants may tip the scales in favor of infection enhancement. Our structural and modelling data suggest that it might be indeed the case for Delta variants."
