[R] Matching colors with lattice auto.key

I try to plot some data with lattice function xyplot. These data are
separated in two groups by a factor. If I let the default color and symbol
settings, I get the right legent with auto.key. But if I change them by col
and pch arguments, the plot is right but the legend still reflects default
settings. Isn't the auto-key feature normally taking its arguments from the
internal parameters of the plot ?
Here some example :
> x <- rnorm(20)
> y <- rnorm(20)
> z <- rep(1:2, each=10)
> xyplot(y~x, groups=z, pch=16, col=c("red", "blue"), auto.key=T)
Is it a bug or am I missing something ?
Thanks in advance.
