Nah. Though we are in China, he's from India. English is more of a second language there and used mainly for business. His English is fantastic. In this situation, I am the native speaker who was insisting my way of speaking was the correct way (that both were correct). I was just trying to help him with his TEFL but I fear I may have irked him by how insistent I was.

There was a study that was done that reminds me of this situation.

In the study, a group of liberals and conservatives were given intentionally incorrect information about important topics in the news (health care, Iraq, tax breaks). Later, the same group was given inarguable evidence that corrected the false information. Instead of being like 'oh, OK I can see that now' the group continued to stand by the false information if it supported their views.

We, as a people, are quite stubborn and set in our ways.....
