When does "range extender" become a "hybrid"?

Some companies sell their vehicles as "hybrid" vehicles, in that they take both an electric plug and fossil fuels to make them go. Some are referred to as "Self Charging Hybrids", as they do not have an external electrical connection to charge the battery.

Other companies sell their vehicles as "Electric Vehicles" with a "Diesel Range Extender". These take an external electrical connection to charge the battery, as well as diesel to fuel the range extender.

For example, when I was looking to purchase a fully electric vehicle recently, the salesperson for one manufacturer literally said to me, verbatim, that their vehicle "is not a hybrid, it's an EV with a range extender."

To the layperson, these could arguably seem like the same thing, as ultimately the "Diesel Range Extender" is, in reality, an Internal Combustion Engine. What is the legal definition that separates these two classifications? Is there a good reason for this, or is it just marketing shenanigans?
