Each scene is told from one character's perspective (point of veiw - POV). You can only get into that character's thoughts. When you jump back and forth between characters, you're head-hopping which is jarring to the reader.
There are some authors that are great at doing that kind of thing. And two I can think of do it in some real epic type stories.
Both S.M. Stirling and Harry Turtledove do that a lot, which is commonly called a "POV Character". However, both tend to be rather careful in how they do it. Their stories can take place in 4 or more locations at a time, with multiple groups. But they almost never interact with each other. Person A narrates their part, Person B narrated a completely different group, that often times never interacts with Person or Group A.
And on the rare occasion two groups meet, say Person C will describe their interactions with Person D, but Person D does not narrate anything until afterwards when he is then passing along their thoughts on the meeting.
But I agree, jumping back and forth mid-scene is tacky and should be avoided. I admit, about 15 years ago I actually played with the concept. It was four or five narration characters, and I jumped between all of them constantly. It was also an experiment in "present tense" writing, as they were all narrating in real time as the events were happening.
But I realized it just was not working, and abandoned it. Not sure if it was the head hopping, or the present tense that was the problem, but I just was not satisfied and never finished it.
