I confirm that from the diag page the same thing happens. I also see that from here the refZ also moves the Y axis though only about 1/2 as much. And both X and Z ref only appear to move Y when Y is close to it's home position. If I move it off home it doesn't move. I am now thinking this is some sort of 'feature' but I don't understand it. Strangely if I do ref-Y then a ref-Z the Y will move about .025. If I do ref-y then ref-X it will move about .05. but if I do ref-Z first the Y will move the .025 and a subsequent ref-X will not move the Y axis at all so Y ends up in different places depending on the order I home the other axes.
If I have the Homing config set to zero the DRO on home everything seems to work and I end up at 0,0,0 according to the DROs anyway. I was trying to get a feeling of how repeatable the Home / Ref position was by doing a ref all with the zeroing active then jogging around and then doing individual axis homes with the zeroing inactive to see if I ended up back at 0 for each when I first saw this come up.
