Omission or Not

Dear folks:

I am in some trouble figuring out the following

sentence structure [underlined italicized].

Could anybody help me out?

... To sum up: Specificity of organic form does not go

hand-in-hand with specificity of chemical composition, and

therefore cannot depend on it; and besides that, specific

organic form is such that it can never be explained by

atomic or molecular arrangement in the chemical sense;

for, to state it in a short but expressive manner, the "form"

of an atom or molecule can never be that of a lion or a

monkey. To assume that, would be to go beyond the

limits of chemistry in chemistry itself.

Q: Does the Underlined phrase mean "To assume that (the preceding phrase)

would be to go... chemistry itself"?

Thank you.
