Because the key goes from top to bottom, while cartesian coordinates
go from bottom to top. Neither can really be any other way by default,
if you think about it. I did promise someone that I would add an
option to reverse the order in key, but looks like I haven't done that

Since we are talking about alternatives, here's another:

barchart(as.matrix(example), stack = FALSE, auto.key = TRUE)
