Identical paintings by two different painters

This is just a curiosity, but I enjoyed it.
Two painters painted the same painting.
No, not 3 centuries ago. In 2004/5.
And not just anybody - Damien Hirst is one of the two (the painter Michael Luther being the other one).
The paintings are reproductions of a news photo.
(And of course, neither artist knew of the other one's project)
Several possible interpretations:
1. Anything is possible in the connect-the-dots painting era.
2. The concept is what counts - and it is quite different in both cases.
3. Great minds think alike.
4. Lazy minds create similar copies of other people's pictures.
Any other options?
