its because the meme sneakily saying more holes (volume) = more holes (percentage), then using transitivity of equality. This equality isn't allowed since the units doesn't match.

Here's how I think is the best way to word it:

There are really two types of "more holes"

The first is the number of holes. Double the volume of cheese and you double the number of holes.

The second is the density of holes. Say the cheese has 1 hole per cubic inch. Double it to 2 holes per inch and you have twice the empty volume

The first phrase increases the number of holes by merely increasing the volume of cheese.

The second phase increases the number of holes by increasing their density.

Cheese is parceled out by weight, so holes are irrelevant.
