Please explain this sentence for me...Thank you ~~~

"the LO pin and ac ground pin of the LO buffer are placed next to each other to minimize the cross-sectional area of the resulting current loop."

so what's the purpose of this layout implementation? what's the advantage of the minimized cross-sectional area of the current loop?

Thank you ~!

The purpose os this layout implementation is decrease the current loop to avoid inteference from the other current loop which is also used the path or partion of the path.
