The difference between the abbreviated notations of AI (repetition signs for 2 last figures) and A (signs for all 3 last figures) could suggest that in the latter all four G notes are supposed to have normal ("big") note heads. According to us, the notation of A is to be interpreted as a simplified version of the notation of AI, which is also confirmed by FE and EE.
In GE1 (→GE1a), the G note on the 2nd beat of the bar is also written as "big", which was corrected in GE2 (→GE3).
