nether portals linkage

hello mojang I would like to report something that happened to me
when I get into my world and create a portal anywhere in the overorld it sends me to a part of the nether but then I go thousands of blocks away from the first nether portal and make a nether portal it sends me to the portal to build first and I find it uncomfortable since it does not send me to a different area in the nether.
but if I build a portal in the nether and I move away many blocks it sends me to a different area of ​​the overorld
If the same thing happens to someone, leave your comment

please mojang to take the time to see this report as it is very annoying
