RVDT - The position of the "upper modes" indicates whether they are engaged on the cyclic or collective channel - collective channel is on the left just like the aircraft! In the 155, L2 and 225 and maybe the 135 (is it 4-axis?) you can have ALT controlled by the cyclic, or by the collective depending on what else is engaged and what your speed is. So its nothing to do with which gauge they are above. I think its more important to know which control is controlling what than to position the display above the gauge. I have never found this confusing.
