The visual flow for dialog is bad. Especially on panel 3. The way the eyes move from panel 2 to 3 has you read the dialog from orange on panel 2 directly to the orange dialog on panel 3. Especially since orange's dialog is higher in the panel.
Convention is to read the highest text first. So it reads as though orange is just unprompted berating green, to which then green is responding to that (that the berating is unfair, not that the race was unfair). When you realize that's the wrong order, and you're supposed to read the lower text first, then it makes sense that green is stating the fault initially and then orange is attacking green for that.
