No it doesn't that if it isn't immediately flagged, that it's ok my friend. It simply means that the Content ID system doesn't contain a fingerprint for this particular game at that time. If you will give me a little bit of time, I'll see if I can find the EULA and tell you what is in it.
Here is the intellectual property section of the EULA; from what I see here, I think you'd better write to them and ask them to clarify before creating videos.
"18. Intellectual Property Rights

I will do a search for YouTube videos in this document when I am fully awake.
