Using Usb from macbook for iMac Installation

Sorry for my english. I installed Sequoia on a 2017 macbook pri recently. Now i got a 2013 imac 27 and used the same Usb. Oclp told me to reinstall macos from a Usb system that matches the iMac moddel. Does it affect the computers performance when i dont reinstall the software? Thanks!
