So i have had this question for a while and I have never known. So in ghusl of jannabat if you perform the tartibi method, You first wash your head and neck and then body (preferably right side and then left).
Yes-same in any wajib ghussl.
So my question is that In the shower when your washing your head and neck water obviously touches the skin and the body.
Yes.
So does that water also clean the body at the same time while you are washing the head?or after washing the head you need completely new water to wash your body.
By clean you mean tahir-ing? If yes, it's fine if it does. Tartibi just means that you start with the head and neck then the rest (not the other way around)**, even if while washing the head and neck the water reaches elsewhere. No, you don't need new water. After making sure it washed the head and neck completely, then do the right and left, even if while doing each side water splashes on the other side it does not matter.
If the second one, how do you not get confused if the water is from washing the head and neck or the new water that has been sprayed on you while you are washing your body.
Luckily it's not the second.. complication removed.
**Messing up the tartibi and need to redo is when for example: you wash head and neck then body, then once you're done you realize there was a drop of say paint or band-aid on your forehead, you can't just at the end wash that off and be done because like this you would have done the body properly then the head, this voids tartibi.
