argument '-C' | question

[Ricky Tigg]

Hello.

Assumed conditions:
$ pwd
/home/<$USER>
$ ls -d
DD

A script working properly contains those strings of code:
tar -xvf DD/00.tar.xz -C DD
tar -xvf DD/01.tar.xz -C DD

As it appears those strings don't have tar command options that follow '-C DD', which then are indications that there does not exist subject to be affected in each string. Since the task of '-C' is to change into directory, as i understand the way 'cd DIR' does, i wonder may those strings respectively equal as follows

tar -xvf DD/00.tar.xz

cd DD

and

tar -xvf DD/01.tar.xz
cd DD

However after

tar -xvf DD/00.tar.xz
cd DD

we would have

$ pwd
/home/<$USER>/DD

Thus, this would make 'tar -xvf DD/01.tar.xz' unable to find 01.tar.xz.

Despite i understand the sentence in TAR(1), Change to DIR before performing any operations. This option is order-sensitive, i.e. it affects all options that follow., i don't comprehend what it is intended to mean to non-developer readers, which i am. I would appreciate if i could receive a definition that would make me comprehend. Regards.
