I thought it would be a good way to illustrate but if it is better that way, I think I could indeed lift the back if I apply the front. Will test.
Anyway, thanks for the answer, indeed it was because it is described as almost nonfunctional that I was a bit surprised!Just for my personal knowledge:
When using a short reach caliper, it is better to have a "road" cable pull to avoid (in theory) pulling to much cable and bottoming out the lever before applying pressure to the rim correct?
So when using a longer reach caliper, supposedly having more cable pull i.e. an MTB should be better?
It works for the use I have it for but it is just to try and understand

You won't pull too much cable, what you can have with a V-brake lever attached to a road caliper is too little pressure at the pads. The further the pads travel for a given lever travel, the lower the pad pressure will be for a given lever force.
So when using a longer reach caliper, supposedly having more cable pull i.e. an MTB should be better?
No, because the other legs of a long reach caliper have already been lengthened to give the same lever ratios as a short reach caliper. Also, you have your thinking exactly ass-backwards - if you lengthen the reach without extending the other arms (e.g. using the maximum reach of a give caliper rather than the minimum), the amount of cable travel for a given amout of pad travel is reduced.

Start with Archimedes.

That's not much of a test. If you can lift the back wheel by applying the front brake, all is well.
The difference in the mechanical advantage of road levers vs. MTB levers is talked up as though it's an insurmountable compatability issue, but it's actually less than the change in mechanical advantage between using a 39-49mm road caliper at the two extremes of its reach.
