take a leaf out of someone's book

Dear teachers,

Would you be kind enough to tell me whether I am right with my interpretation of the expression in bold in the following sentence?

“Eighteen thousand “ said he. “And fifty” said Jim, taking a leaf out of his adversary’s book.

take a leaf out of someone’s book = to behave or to do something in a way that someone else would; follow the example of; imitate

Thanks for your efforts.

Regards,

V

Yes, you are right
