If I cut a thing in two, are the two pieces together exactly the same size as the original?
Or to rephrase it: does a knife/scissors/etc just split something or does it remove something?

I believe, chemically, molecules with a stronger bond push molecules with a weaker bond apart. And physically, the applied force over the affected area decides the amount and direction of the bonds being separated.
In most cases cutting causes a physical change not a chemical change.
I believe when they say chemically they are referencing, “at a molecular level”
