high precision YUV rendering

May seem a excessive....

I have a long project and I have decided to divede it in smoller videoclips for the final dvd, so I created new sequences for every new videoclip (portion of the previous bigger one). The original was rendered in high precision YUV and I forgot to modify the settings in the new sequences before pasting. I pasted, then modified the settings and then re rendered... is it ok anyway? I noticed that if you paste after changing the settings no rendering is required - I just want to be sure that the final result is the same.

Thanks
