Given that you overwrite ABC before you print it in script 2, ABC will always end up "xyz.txt" in that script no matter what it was before. Their values aren't protected in any way. But that's beside the point...
Variables don't travel "sideways" like that. They don't actually travel at all -- each and every program has its own, independent set of exported variables, called the 'environment'.
When you run a script or program, it gets a copy of your current environment. But the copy is unconnected. Change the child and the parent remains the same, and vice versa.
If you wanted the same variable to be set in two different programs, either set it earlier in your ~/.profile or ~/.bashrc file so it gets exported on login for you, or have a little config file thing for your scripts to source:
The "." operator runs the given script inside the current shell. This is very different from just executing './littleconfigfile' because . allows you to set your own variables instead of setting variables in a useless copy.

git-var
GIT-VAR(1) Git Manual GIT-VAR(1)NAME
git-var - Show a Git logical variable
SYNOPSIS
git var ( -l | <variable> )
DESCRIPTION
Prints a Git logical variable.
OPTIONS -l
Cause the logical variables to be listed. In addition, all the variables of the Git configuration file .git/config are listed as well.
(However, the configuration variables listing functionality is deprecated in favor of git config -l.)
EXAMPLE
$ git var GIT_AUTHOR_IDENT
Eric W. Biederman <ebiederm@lnxi.com> 1121223278 -0600
VARIABLES
GIT_AUTHOR_IDENT
The author of a piece of code.
GIT_COMMITTER_IDENT
The person who put a piece of code into Git.
GIT_EDITOR
Text editor for use by Git commands. The value is meant to be interpreted by the shell when it is used. Examples: ~/bin/vi,
$SOME_ENVIRONMENT_VARIABLE, "C:Program FilesVimgvim.exe" --nofork. The order of preference is the $GIT_EDITOR environment variable,
then core.editor configuration, then $VISUAL, then $EDITOR, and then the default chosen at compile time, which is usually vi.
GIT_PAGER
Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the
$GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually
less).
