Is the Pod headphone output stereo?

Just starting out with the Pod and got some simple Pd patches running with pd2dsy, but the output from the headphone jack always seems to be mono, is this normal? For example the patch “pod_test” has a different oscillator coming out of the left and right channels, this works fine from the line out but is a mono sum on the headphone jack.

Yes, the headphone output is stereo.
