Yes, good catch. There is a difference. In the monkey cell line B directly inhibited SARS-CoV through disruption of the viral envelope. In today’s kidney cell line, the report stated B prevents cell entry “ by blocking the SARS-CoV-2 Spike 1 (S1).”
However, it goes on to say “We now have preliminary in vitro data from two separate independent laboratories that, cumulatively, support Brilacidin’s ability to act directly on the novel coronavirus, as a virucidal agent, and prevent viral binding to host cells.“
So, the report confirms two actions of B, it is both inhibitory and virucidal.
