That's like saying a burger is plant based since the patty and cheese are the only non-plant based parts. That's ridiculous and just not what the word plant-based means.
It all depends on what is actually trying to be communicated. With your definition most meals would be plant based so why even bother to say it. With definition where plant based means no animal products it communicates that it is fine for vegans and it's likely less offensive for people allergic to word "vegan".
