"The example was not leading" -- definition of "leading" here?

Question

I have come across the expression "unfortunately, the example was not leading" in the context where someone asked a question accompanied by an example and someone provided an answer that addresses the specific example but not the question in general.

Given this context I understand what "the example was not leading" conveys. It's also easy to see a parallel with e.g. Wikipedia's definition of "leading question":

In common law systems that rely on testimony by witnesses, a leading question or suggestive interrogation is a question that suggests the particular answer or contains the information the examiner is looking to have confirmed.

So by the same token "not a leading example" would mean "an example that does not specifically illustrate the particulars of the problem".

My questions are:

1. Is this a well-known expression, just as "leading question" is?
2. Is the definition I reached above correct? If not, what would a better one be (with references if possible)?

Answer 1

A leading example is one, that allows to correctly build some kind of rule on it. It leads to a conclusion.

If you drop a cat several times in front of class and it lands on it's feet every time, this is a leading example for the agility of cats.

Answer 2

"the example was not leading" for better understanding we can write that "the example was misleading"

Basically, misleading means

"the wrong idea or impression".
