What is the meaning of al-Haythami's statement in Majma' al-Zawa'id: "Its narrators are trustworthy" or "Its narrators are highly trustworthy"? Does this make the hadith authentic?

The Shaykh : ... Its narrators are trustworthy; therefore, it is not permissible, from a scholarly standpoint, for a writer to cite the authenticity of a hadith in a specific issue based on the statement of "al-Haythami" or other scholars: "Its narrators are trustworthy." It is not valid to use this as evidence for authentication, because it only signifies the presence of the condition of authenticity. This is what is meant by the phrase: "Its narrators are trustworthy," and even more so: "Its narrators are highly trustworthy" does not confer authenticity. Rather, even if the chain of the hadith in which "al-Haythami" or another said: "Its narrators are highly trustworthy" were free from every defect except for this statement: "Its narrators are highly trustworthy," that would mean: be cautious, be alert. Among these men, there is one who has issues. So investigate and verify. And from my personal experience, I know that he says: "Its narrators are highly trustworthy" when there is a man in its chain who was vouched for as trustworthy only by Ibn Hibban, and there is discussion regarding his vouching.
This is my answer.
