Parts that are assembled require engineering calculations to insure that the Parts will not fail under shear or Bending.
If 10 Fasteners will prevent failure of the assembled structure, then the 10 holes can be about the same center line.
Should the assembled structure require addition integrity, the hole pattern for the fasteners will be on an off set or straddled center line.
This is a standard engineer practice in Bridge construction and building construction.
I use the Term Fasteners as general term here. Fasteners can be Bolts, washers and Captive nuts...They can also be Rivets.
Hope this answer assists you.

Straddled holes prevent shear and other forces from concentrating on a line through bolt holes that are alternatively drilled in-line. Holes weaken the steel or other material being fastened.
Hope this helps!

Straddled when there is a Motion about some axis... to avoid shear & bending moment, etc..
In-line when there is no motion, regardless of movement by human hand or carry, or etc.

depending upon the work performed upon them the design of the bolt hole is made.. correct me if i'm wrong .... when u get the right answer....
hope i helped u....

If I'm reading your question right, it may be to permit a vernier length adjustment
