Agreed, they look like two different people. I'll try to find to find the vcd and confirm the HKFA credit for How Two Naughty Girls Thrice Insulted Xiao Yuebai

Can't place my hands on the vcd at the moment. But looking at Vols. 3 and 4 of the Filmography, there are photos of three different people, two women and one man, identified as Leung Mo-Sheung!! Confusing, indeed.
I'll update with the references here in a bit.

Looking closer at the photos, perhaps, like Yam Kim Fai, Leung Mo-Sheung specialized in female as male roles?

Vol. 4 -
#487 - Chan Sai-Mei and Chun Heung-Lin ( as a man?)
#614 - How Wong Fei-Hung Thrice Tricked the Lady Security Escort (disguised as man)
#699 - Tonight and Every Night (as female)

Vol.3 - If you look at photo on p.482 (New Sit Ting-shan Thrice Tricks Fan Lei-fa ) you can see the transition in images from Emperor's Sacrifice to Two Naughty Girls.

So, I guess I'd say they are the same person.
