Fatal Love (1988): 2 part question

Per Fatal Love (1988)

I am curious as to what the below credit implies in relation to the film? We have Benny Chan listed as an "executive director" -- here's his screen credit:
And the reason I bring this up is that if he was infact the film's "acting" director, then this would be his first screen credit as a director (two years prior to his generally accepted debut with "A Moment Of Romance"). My hypothesis comes from some reading I did over the weekend (a two part interview with Ringo Lam in [now defunct] Australian cult film magazine "Fatal Visions" circa 1994), as I discovered that Ringo Lam's first directorial effort ("Esprit D'Amour") was actually one where he was brought in to complete an unfinished film...after Cinema City head Karl Maka sacked the existing director, Leung Po Chi! If Maka had had issues with Leung on prior shoots and, "Fatal Love" being a Cinema City production, similar creative differences arose herein -- maybe Benny Chan was the actual director of this film?
HK film productions are notorious for NOT fully crediting a film's direction team in the instance where one well-known director was hired but later sacked or left the project for whatever reason. Neither Eric Tsang or Stanley Kwan were credited for their work on "Armour Of God" nor Johnnie To on its sequel, and Lau Kar Leung retains sole director's credit for "Drunken Master 2" though it's a well known fact that he and Jackie Chan clashed on styles and Chan directed most of the film.
Anyway, this is one of the few times in memory that I can recall having seen an "Acting Director" credit precede the accredited director billing. Anyone have any ideas? The film certainly looks and sounds exactly like a Benny Chan film would have circa the era (some of it bears a striking similarity to Chan's later "Moment Of Romance").
