The confused commenter clearly comprehended the argument to some degree, but a few possible details were overlooked.
I think your example is bad. It’s the first commenter who is confused, not the second one.
The correct formulation is “If, for any small positive number (epsilon), I can show that the difference between A and B is less than epsilon, then I have shown A and B are equal.”
The first commenter screwed things up by saying “If, for any small positive number you give me (epsilon), I can show that the difference between A and B is less than epsilon, then I have shown A and B are equal.” The second commenter’s objection is valid.

Agreed. I should take it out.
