It is the same two experts. Both links are based on the same source.

I like this quote from Sandra's link:

"It remains to be seen how widely accepted this new theory about the origin and meaning of the Cerne Abbas giant will be. Those who've invested time and energy pursuing other explanations may not be ready to give up just yet. This isn’t the end of attempts to understand the meaning of the Cerne Abbas giant, since conclusive proof that the giant is actually Hercules is lacking, as Drs. Morcom and Gittos concede."
