The term is used in carpentry and in that context it is a way to join two pieces of wood. You cut a series of "dovetails" in the wood which are kind of like a truncated "V".
The term is also used to describe any two things that fit closely together, either literally or figuratively.
I can only imagine that in this cookware, there is some process in the manufacturing where two pieces (handle and pot perhaps?) are dovetailed together.
Dovetailed is a way of bringing the copper together at it's open joints. Certian copper cookware, Mostly older ccokware had some dovetailed finishes applied to them. This makes for a very well made piece of cook ware. Dehillerin is one of the finist you can buy. You will pay a heafty price for them,but you will never replace them.
The dovetail effect looks almost like tounge and groove.
