I looked at it again and everything looks the same as it did back then (a few months ago when the pics were taken). The other thing is, based on the pics I've seen where it was known that the steerer tube cracked from overtightning.... this one looks different.... it doesn't have any split heading towards the outside, I'm not exper but that's my "observation".
Also, I got a response from the original owner and this is what he said:
"It is probably caused by pressure from the top cap not being well distributed across the cut surface of the steerer tube. Usually this sort of problem is limited to a small section above the compression plug. If it doesn't extend too far down the steerer then it's probably safe to ride. The important thing is to make sure the steerer is solid in the section that the stem is clamped."
Has an1 ever heard of that happening? And how does the pressure not get distributed?
And this fork apparently costs 500!? That's bizzare!!!!
