When I went to the UCLA lab a few months ago, Prof Putterman said that
the light appeared to have a overall macroscopic polarization pattern,
which you would not expect from independent atomic recombinations, but
rather pointing towards some overall collective phenomenon.

I don't know what more recent experimental results say.
