I agree that the luck is probably better represented this way for a
single match length or a money game session. But the same argument
could be made for the error rate, i.e. should your errors be measured
in relation to the amount of match equity that you loose rather than
the amount of EMG. The reason that it is done this way for error rates
is obviously to be able to keep just on statistic independent of match
length. To me the error and luck are very similar, i.e. it doesn't
matter if you loose 0.2 point by bad luck or by making a major
blunder.

That is the explanation, I believe, for the layout being as it is. But
I agree that the labels could be clearer, for example

Total luck - ME (EMG) == Luck rate (total)
Luck rate - ME (EMG) == Luck rate (per move)
Total error - ME (EMG) == Error rate (total)
Error rate - ME (EMG) == Error rate (per move)

(where ME == ME or points. The term Luck rate(total) is certainly meaningless.)

with these clearer labels I believe that we can interchange the the
values as you and Ian wish.
