'terms' and 'merely', how to understand them?

Finally, they all begin to understand the process in the same terms.

I have come across this sentence at the above link. I don’t understand it. Some said the word ‘term’ should be understood as ‘way’, some thought it was ‘specialized word’.

I want to know what’s the meaning of this sentence, its structure and how the word ‘term’ should be understood.

Another sentence:
It has long since been satisfactorily established that a high executive does not have a large vocabulary merely because of opportunities of his position. That would be putting the cart before the horse.

Does or does not the high executive have a large vocabulary? Does ‘merely’ have negative meaning? What does ‘merely’ contribute here?
Thanks in advance.

I apologize to anyone who is upset by this thread. I placed it in the wrong place and I don’t know how to delete it.

1- It's similar to way, but implies, to me, that there are a number of conditions for this comprehension.
2- It as a meaning similar to just/only- other words, the executive's vocabulary is not dependent on their having that position

PS- I'll move this thread.

Thank you.
