A link is a link, just like in Windows.
So when you enter the house at cd /softlink you actualy enter /main_dir, seeing the very same files.
Deleting a file in /softlink will also remove the file in /main_dir.
EDIT:
Or in other words, consider the /main_dir a house at a street cross.
If the house was only at one street, it would have just one door.
But since its sides are at two streets now with the symlink, it has two doors as well, which both are leading to the very same rooms (dirs and files) within the house/folder.
EDIT2:
The only 'non-original' file is the symlink /symlink, which represents a folder (/main_dir)
All other files are 'original'...

LCHOWN(3) 1 LCHOWN(3)
lchown - Changes user ownership of symlink
SYNOPSIS
bool lchown (string $filename, mixed $user)
DESCRIPTION
Attempts to change the owner of the symlink $filename to user $user.
Only the superuser may change the owner of a symlink.
PARAMETERS
o $filename
- Path to the file.
o $user
- User name or number.
RETURN VALUES
Returns TRUE on success or FALSE on failure.

<?php
$target = 'output.php';
$link = 'output.html';
symlink($target, $link);
lchown($link, 8);
?>
NOTES
Note
This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.
Note
When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script
that is being executed.
Note
This function is not implemented on Windows platforms.
