Maybe one of those occassions where the theory and practice don't match?


Theory and practice always match, if it appears otherwise then you've
misunderstood the theory or there's some other factors involved that you
weren't aware of. The use of shunt capacitors acroos the replay heads of
analogue tape machines to boost the HF response was standard practice, often
these capacitors were switched according to the speed selected with larger
capacitor values being used on the lower speeds.
