If you meet the Buddha on the road, kill him!

There's an old saying, "If you meet the Buddha on the road, kill him."

Who's that Buddha? What does it mean to "meet" the Buddha? What does killing the Buddha imply?

If you have studied Zen or heard about this, you may have come across this very classic koan and have mulled on it as what it means to "Kill Buddh"? Or what it implies?

I am still on that koan a decade after I heard that.

Just google and you will see this koan and endless explanations on it.

I have a similar koan.

Background: Buddha originated from what is now known as Nepal and spoke Dharma in various parts of India. Though he spoke Nepali at home, wherever he went, he spoke in the (native) language of the country he was in. Mostly it was in NePali, Pali or Ardha Magadhi.

Buddha's followers later tranlsated them in to myriad languages. He wanted the teachings to be taught in a language people understand.

Given this background I have this koan:

Buddha comes to America! He was requested to give a Dhamma talk and he agrees. Buddha mostly spoke in Pali or Ardha Magadhi. However he knew American! He notices that among the audience nearly half or more only understood American. The other half understood both American and the languages Buddha knew.

Would Buddha give his Dhamma dispensation in American? Would he be parochial and speak only in the language of his tribe? Or would he out of compassion be bilingual and speak in two languages to maximize the transmission of Dharma?

What do you think?
