Thanks Kurkio, got the shift-F1 thing undercontrol.
I was mainly interested in the R/L reasons for the offset.
Your explanation that it was to put the sight in front of the right eye sounds reasonable, but the offset appears to be significantly more than would account for that.
Also, as humans have binocular vision I dont see any real benefit to having it directly in front of the right eye only.
In fact I can see it being a disadvantage to those whose left eye is stronger.
