Correct. What overlining does is slow the timing of a given casting length.
However, it does nothing about the fly rod's action. For example, a fly fisher may want a slow action rod with a softer tip because it protects delicate tippets better. But overlining a fast action rod does nothing to change the stiffness of the rod tip or anything to change the overall rod flex so that it bends more easily to protect tippets. Once the cast is made, you have the stiffer rod you didn't want in the first place.
So if a person wants to slow the timing of a faster action rod to his/her casting stroke; they have purchased the wrong rod. What this really means is that the caster is unable or unwilling to adapt his stroke mechanics to the fly rod.
Yes, you can sometimes pound a square peg into a round hole by using a bigger hammer than you would normally need; but wouldn't it be easier to use the correct hammer and a round peg that fit. Overlining is kind of like using a square peg (the faster rod) with a larger hammer (the heavier line).
