How do you think a case of “this explains some of the differences in the population, but not a lot” should look?
And that looks potentially fine for an error bar. For a mean estimate, SE=SD/√N , so depending on what error band they used this looks quite plausible.

Take a look at these examples of regression. See how any one of the conclusions is absurd? Mind you the data in that example is far less random!
Also, the R^2 is even in the picture: .11
