No,it was market after he posted,you can see the nest post of him,still it says open. 
Looks like you need some teaching in how SMF works.
It was Open in his post because he quoted a post in which the original subject was used.
You can modify the subject each time you post.
Only when you hit "reply" or quote the OP the modified subject from OP will be used.
Look harder before lecturing others next time.
