What you can see is Sands Street and its steps that lead up to Ching Lin Terrace. I guess having two locations close by is handy from a logistical (and money) point of view so it wouldn't surprise me if these two scenes were filmed around the same time?
One thing I have noticed about this film is that Rob Cohen, the director, doesn't seem too fussed about including modern anachronisms in the film and, at many points, much more modern buildings can be seen in what is supposed to be 1970's Hong Kong. Still, it does mean that we see a lot more of Hong Kong than we would have otherwise. A good example of this is the building on the right (with the arched doorway) which was actually built in 1991 and was probably brand new when this film was made. I haven't got a matching angle, but this Streetview grab shows many of the same buildings are still around.
