In Regression course serious error or my missunderstanding? X,Y switched in graphics

In Trading with Machine Learning: Linear Regression course, Section 4: Regression, chapter 4:errors and Residuals, the graphics of X and Y (dependent and independent) got switched on purpose or by error? The horizontal line X (video at 3:34) was representing the independent and all of a sudden (video at 3:44) the label got switched  and became dependent. The same happened to the vertical line Y- first it was independent and then became dependent. 



Was that by error/mistake on the part of labeling X and Y by the graphic designer? Or am i not getting something? Why were they switched?



Kindly address the issue, please, if it is faulty graphics or my missundesrtanding, since for good undesrtanding, when it comes to beginners, pulling the rug from under the feet is rather cruel joke. 

Course of this quality should not have such errors, if so.

Or, if i did not understand, why all of a sudden there was a need to swiitch axes?

Thank you!
