If Meat Eaters Acted Like Vegans - cucumber, a cucumber, the cucumber

[GhotiO |fɪʃ|]

In the video If Meat Eaters Acted Like Vegans - episode 35 on Youtube, JP says:

• This sausage is a meat-based vegetable substitute for cucumber. It's got the taste and the texture of an actual cucumber, with none of the cucumber.

In these two sentences, he says cucumber three times, each of which has a different article: a zero article (1), an indefinite article (2) and a definite article (3).
I don't understand this at all. Did he use them correctly? Why not just use an indefinite article in each of the three instances? Why a different article each time?

Yes, they're all correct.

The first and last are about cucumber as a substance. The middle one is about the vegetable itself.

You seem to have totally missed the humor in that.

If so, why do the first and last ones differ in the articles? I mean if they're both about cucumber as a substance, why different articles (a zero and a definite ones)?

On this particular forum this is my first account.

Why do you think I seem that way to you?

The sentence could end "with no cucumber" and then you would have no article. The form "none of the" requires the article.
