[R-sig-ME] Why || doesn't zero out the correlations in lmer

I have a 'factor' predictor called 'type' (with 4 levels). In the
random part, I have used `||` so the levels of 'type' can't correlate
with each other.
But I wonder why still correlations are reported in the output?
lmer(y~type + (type || ID), data = data)
Groups Name Std.Dev. Corr
ID type0 0.4276
type1 0.7012 0.81
type2 0.7115 0.72 0.97
type3 0.7655 0.83 1.00 0.98
