If you mean the US CBP officer would find it abnormal that you don’t have an exit stamp from wherever you are coming from, then the easy answer is: they won’t:
Unless they become very suspicious for some reason and start splitting hairs, the chances they will notice (which would require them flipping through all the pages of the passport looking for an exit stamp from the same day and not finding one) are zero.
They know perfectly well where you are coming from: the airline will have sent all your data to them before you are even allowed to board, so they will have all the info. And they probably don’t care much what your status is in wherever you are coming from. What they want to know is:
They are interested in you having a return ticket (which, again, they will probably know about if you have both flights on the same ticket). They may ask about how you will enter the country you are going to at the end of your stay, though I’m really not sure this is something CBP officers ask for. Showing your residence permit should be enough for that. They may be puzzled by the different spellings, but they probably have seen worse.
