it's backwards in a "numerical" sense, in
that the numbers increase with
one slider type, but decrease with another, using the same command.
However, UI designers don't think in numbers, but associations.
Left is generally associated with up, right with down, as we read left to
right, top to bottom. Therefore, up MUST map to left, down MUST map to
right, otherwise, non-mathematically minded people get uttely confused.
this doesn't seem right to me. in all countries that use left->right
writing conventions, i think right is considered the default
"up".
also, when i think of road driving signs used to indicate significant
uphill or downhill sections, my recollection is that in the US and in
Europe they obey this right=up association if they actually show the
slope.
