They could have done a very small run, it could have been a test press. They could have thrown out most of the stock and only had a few stray file copies. This is actually the most likely explanation, as if you encounter producers this is what happened 95% of the time -- they don't see some future value in boxes and boxes of old records that are just taking up space.
They are also very irrational. If not one of the above, who knows what their reasoning was? Either way, they just repressed the exact same record on a brown label and it looks like their other represses. It makes less sense to do that if they managed to do a run that looked like earlier presses and have quantity of it.
Also, Gold of my Life is the b-side of this record, the a-side is "down and out", they might not even have considered it as the same record.
