It can. Also "he will come to us" (the same way "he is coming" in English can indicate future) .
The question was to translate "הוא בא אלינו" into English. I entered "he came to us" and it said I was wrong.
No worries. I happened to read discussions, but next time please use the report function (unless you have a question).
he will come to us "הוא יבוא אלינו". the slang "הוא בא אלינו" to express that someone will come is wrong
