When I took typing in high school (mid-80s in the US), on an IBM Selectric, we were taught that way. If the key you wanted to capitalize (or needed the shift for) was on the left hand, you would use the right shift key and vice versa.

I didn't know it at the time, but that one semester class was immensely useful for me throughout my career.

I took typing as an elective class in school in Denmark fully expecting it to be useful for decades. And I was right :)

The teacher was a bored and unpleasant secretary and the typewriters were mechanical (and the shift keys so heavy for our pinkies) but it was still the most useful thing I did in school since I learned to read in first grade.
