thats fine, it is totally outside of the scope of explaining behaviour, which was the point of the study.
"Altruistic behaviour" is normally defined as behaviour that appears to have a cost for the actor that is not related to any particular reward. Historically, this has been a problem for philosophy because of, exactly what you are saying.
In science though, people are less concerned with what the philosophical-linguistic ultimate meaning of the symbol "altruism" is, and more with what motivates those behaviours.
The reason I personally don't think it matters is that the English language wouldn't look remotely similar if all of the words used had to follow strict scientific definitions.
Whether something can ever be done with no sense of self (no) is rather moot, imho, in anything but the most academic philosophical discussions of the term, as we all generally know what "altruism" means when it is said.
Also, if I am not mistaken, altruism is almost always referred to as "pro-social behaviour" in scientific literature.
