I think you need to define some of the terms you are using. Why?
Most Eastern philosophies and Americans who reference them, as well as many men and women and (mostly female) websites that think they are doing a good service, consider a male multiple orgasm as an orgasm without an ejaculation. IOW, stage 1 (emission) of the male orgasm but not stage 2 (ejaculation). The point is to repeat and eventually learn to stay in stage 1 without cresting over into stage 2. It is reported that a man will obtain "higher states" as well as full body orgasms by using this technique. However, in reality, this is simply edging. Unless you ejaculate, you are robbing yourself of half your orgasm
and frustrating the shit out of yourself!
Now, if you edge a bit too far but, as you say, you relax, in addition to your internal orgasmic contractions you actually feel the first few ejaculatory contractions as your cock begins to contract as well, upon the third or 4th cock contraction, you begin to shoot semen. Is this what you mean when you say you cum in #4? If so, then yes you are but because you are greatly relaxed and have not had a full on total ejaculation, your refractory period does not kick in. In reality, you really have not released the endorphins that are produced with a full on ejaculation that start the chemical process that causes the refractory period. So, you can maintain your erection and do it again, in theory, indefinately.
Problem is, for some men, without a full on ejaculatory orgasm they don't feel total fulfillment. I can do that maybe 1 or 2 times and then boom, my frustration level and need to ejaculate big time takes over. A man is biologically wired to ejaculate.
There are documented cases of men that have **true** multiple orgasms where they have full on, no relaxation, average number of spurts, ejaculations with each and every orgasm without loosing their erection. See
True Male Multiorgasmic Response -- Study Overview with a documented case of such a man and according to a book, The Science of Orgasm, there are other documented studies that prove men can indeed have full on ejaculatory orgasms and not have to hold back. These are true male multiple orgasms.
IMO, if you have to relax or change your thoughts, or in any other way slow down or stop the natural need to ejaculate with orgasm, you are only cheating yourself of pleasure and are not experiencing a true male multiple orgasm. Not that there is anything wrong with that! Edging is good too and it will eventually produce a stronger, more voluminous ejaculation but it really is not a multiple unless you go all the way, stay hard, and then go all the way again. Ask any woman if she is holding back and I'll bet she says no.
Namaste
