i know smeagol and gollum are basically the same person, but what does it mean in this meme?

Answer: 
When somebody is standing in front of a crowd and they say *left* or *right*, it's almost always in reference to the perspective of the crowd that is being addressed.

A teacher may turn and point to the blackboard, indicated something to the left or right as they are *now* facing.

In theatre, if an actor or director wants to talk about things from the perspective of people *on the stage facing the audience*, they use the phrases [**stage left**](https://www.merriam-webster.com/dictionary/stage%20left) and [**stage right**](https://www.merriam-webster.com/dictionary/stage%20right) (from Merriam-Webster). Note that that is not spoken to the audience; it's for stage direction behind the scenes and during rehearsals. The audience uses the normal words.

So, the assumption is normally the perspective of the audience.

But if it's unclear, clarifying language can be used.
I think the students will look at it form **their** perspective. Unless something warns them, the audience will likely look at it from their perspective. An experienced orator would be aware of this and pick their words carefully.

To clarify, the teacher (as he stands in the picture, facing the class) might say ***my*** left-hand side (yellow), or ***your*** left-hand side (red).

As I suspected, there is a distinction. I don't know anything about hearts and muscles, but that doesn't matter. The speaker is using the **middle** of the image to distinguish the left and right sides. As a casual observer, I understand his words to mean that he is talking about the purple and yellow figure. Whether or not it is accurate is not a matter of English usage.

There is also the possibility that he is referring to the entire image. Before the video cut to this image, he was standing to the right of the image, facing the viewer. If in his mind he does not know that the video will cut to this image, and he has a live audience in mind, then referring to *the left-hand side* would be with respect to the audience's perspective and it would include the entire image.
