what is the difference of create and delete in synchronization

[theuser]

what is the base difference for a file to be deleted or copied ?

One of those actions creates something ane the other deletes something

yeah but what is the difference between the delete line or create line if they both can do the same thing
and how does it decide between variations like that?
lets say i have a file on only right side , how does it decides if itll be moved to left or erased? because i feel like create line and delete line are just symmetric which means nothing

please enlighten me , im confused(im not sarcastic btw , im just curious and confused)

This chart is a "event+location=action" chart
The bottom picture, for example:
- If a file is created on the left side, then copy to the right
But for the top two pictures:
- If a file is created on the left side, then delete from the left side

i see , but what is the difference between top 1 and 2? i mean there should be some difference?
as far as i can see create and delete is just mirrored versions of each other which means nothing to me

The first one is:
If a file is deleted from the left, then copy item from right to left

The second is:
If a file is deleted from the left, then delete item from right

The top one is "Oops, I deleted something from the left side and I want the left side to equal the right side."
The bottom one is "I want the right side to look like the left side, so delete anything on the right side that I delete on the left side."
