Pretty much. Common technique in character design is to draw a character, erase back most of the drawing, then draw back over it but with variations. This is not to trace the original but to try and improve it.
You will be using it to get closer to the drawing you are copying but it is mainly used for experimenting with and improving designs.
I'm a fan of Aaron Blaise's tutorials as they are very accessible. His character design course is well worth the investment. Here is a sneak peak where you can see him do this sort of process digitally but is effectively the same thing. Worth following his youtube livestreams too which he does most Fridays.
