The reliable information is the picture - blood doesn't run up. Woodcock clearly made a mistake. There is a trail of blood that has run from her mouth, up to the eye and from her left nostril up to the eye (a bleeding nose would also run DOWN her face, not up), the blood has then pooled under the eye which has then run down past the outer corner of her eye. This couldn't happen if she had been sitting up. You don't need to study to degree level to know that blood can't run UP - the only forces that would make it do so have to be supernatural. You can see that the blood has run up as opposed to down because of the small amount of blood that is running from the right nostril - see below. You must have had a nose bleed before - I bet it never ran up your face?
The picture is at odds with testimony from a first respondent and forensic scientist so no I don't find it reliable at all. I find the picture highly controversial!
Your interpretation of the blood trails above is that blood run from her mouth to her eye. Dr Vanezis' autopsy report contradicts your interpretation. He states:
"There was blood around her mouth which had run down her face in a vertical direction. In addition there was also a small amount of blood around her nose":

If SC's head was flat to the floor following the 2nd fatal gsw then surely the blood we see from her nostrils would have pooled in the bridge of her nose or that area?
Based on info from first respondent, pathologist and forensic scientist it seems the blood trails on SC's face were entirely consistent with her head slightly raised/propped up against NB's bedside cabinet with blood running down vertically run from her left eye and nostrils.
