Hi Klearchos, Since Luis has reproduced your issue, I came back on it (thanks, Luis).
When *-progression-dimension.maximum are equal, the issue comes when a square image is used. Please, can you fill in an issue on Bugzilla, providing the attached short test case (FO + 2 jpeg). Workaround: as Luis said, different values for *-p-d.maximum give expected result. Note that on inline axis, you can use percent values, since it is computed regarding the i-p-d of the parent FO element. So, as a good practice, you can set i-p-d.maximum="100%". This is not applicable to b-p-d axis, since the b-p-d of the parent element depends on its content.
