I noticed that the chrono second hand and the split second hand are not in-line.
This demonstrates the possible effectiveness of one the new changes in the 5204:
Patek has taken care of the matter that big forces are working on the split and chrono hands when they are set back again.
The hands can act like a whip and bend over the zero mark.
When I was reading about this new patented feature of the in-house chrono I was wondering about the practical meaning as I do not own a PP chrono and aslo not a split chrono.
Your picture, which is a lovely, lovely shot, explains it.

That the hands are differently wide is something I can not judge or see as I do not have any of the two watches.
The "play" of the hands is mentioned in reviews and as you are saying are an essential part of a mechanical watch.
Speaking for both watches:
the 5004 is a cult Patek.
The 5204 is a the technical cult object as it takes a very, very small detail in consideration and solves it magnificently.
I was thinking that Lange's DS is THE technical marvel but Patek has gained a lot in the split second chrono race (
) with this 5204.
