I am guessing he is planning on returning later, right? Don't you think he is going to have trouble coming back if his departure hasn't been recorded?

Sorry, I don't have any personal experience or knowledge on this topic. Just wanted to let you know that the above question was the first thing that came to my mind. Also, I don't think "Urgent Help" is the appropriate title for this post.

This isn't exactly your question but this might be helpful:

I did not turn in my I-94 when I left the U.S., what should I do?

If you returned home with your Form I-94 (white) or Form I-94W (green) Departure Record in your passport, it is possible that your departure was not recorded properly.If you departed by a commercial air or sea carrier (airlines or cruise ships), your departure from the U.S. can be independently verified, and it is not necessary to take any further action, although holding on to your outbound (from the U.S.) boarding pass - if you still have it - can help expedite your reentry next time you come back to the United States.If you departed by land, private vessel or private plane, you will need to take steps to correct the record. If you do not validate your timely departure from the United States, or, if you cannot reasonably prove you departed within the time frame given to you when you entered, the next time you apply for admission to the U.S., Customs and Border Protection (CBP) may conclude you remained in the U.S. beyond your authorized stay. If this happens, your visa may be subject to cancellation or you may be returned immediately to your foreign point of origin.

I 94 ta US bata bahira jada bujaunu parne hoina ra. pheri US bata bahira India wa China ja gayeni I94 le US chodeko date dekhaihalcha ni. whats the point in going Nepal via India?ani boarding pass ma pani ta date huncha ni?

That is what we do, we missed the deadline and now we want to correct it. Once overstayed it is done deal, I guess so. 

It matters is the timing that is stamped at the Entry Point, not the visa given by the counselor at Kathmandu.
It may sound bad but the truth is " हगी पनि सक्यो अनी बाटो देख्यो "
