It is NOT a black hole at all in one direction, it is in the other.
The same for pragmatist. THAT was the question.
And that was my point: you can't have that scenario. If you have an event horizon, it's closed. There is no 'other direction'.

As mister shminux mentioned somewhere, he is happy and qualified to answer questions in the field of the Relativity. Here is mine:
A long rod (a cylinder) could have a large escape velocity in the direction of its main axe. From its end, to the "infinity". Larger than the speed of light. While the perpendicular escape velocity is lesser than the speed of light.
Is this rod then an asymmetric black hole?
