That quote is quite different from the definition you're using.
Your definition is not what anyone else uses, from what I've seen. You don't have to use the same definition, of course, but be aware that unless you clarify what you mean, you're going to be creating a ton of confusion.
I don't see how it is different. A "higher level of abstraction" means progressively higher-level versions of source code. Binary->machine/assembly code->C++ code for example. Each step involves reverse engineering. Simply disassembling/decompiling a binary is not really sufficient to be considered "reverse engineered". Someone needs to analyze the output of these tools to create reverse-engineered output which is ready to be modified/extended/investigated.
