Eleanor, whom are you grumbling at?  If it's at the depositors, here's a 
counter-grumble:

How would a depositor even know????

  *   know that it's "wrong"
  *   know what definition of "wrong" to work towards
  *   know that someone somewhere will care about this particular "wrongness"
  *   know that visualisation or analysis software does not elegantly deal with 
this - it is after all 2019 already

If I had to prioritise wrongnesses, I'd put top of the list that it is not as 
absolutely trivial as possible to get data into the public domain.  Which means 
working hard (even harder!) to remove all arcane things from the ecosystem.

Dear Eleanor,
From PDB files I see that  the structures were solved by molecular replacement 
using pdbid 1gci as a starting model. It is hard to say definitely without the 
linked paper but may be the depositors made the same error that I did some time 
ago: they solved both structures using molecular replacement instead of running 
rigid body refinement for follow up structure.
Actually, the issue with different origins is pretty common in pdb. For 
example, I searched pdb for isomorphous lysozyme structures in P43212 with unit 
cell dimensions a=b=78.5-79.3 and c=36.5-37.3 and have found 121 structures. I 
picked 6 random structures and only 2 of them have the same origin.
By the way, may be someone has a script to move several isomorphous structures 
to the same origin and rename chains according to reference structure?

I have just downloaded two isomorphous coordinates from the pdb
5arb and 5arc  deposited by the same team


Tried to compare and they are on different origins.

I know it doesnt affect the crystallography
It is easily corrected

BUT it seems bad practice to me
