Duplicating mc using array

Okay,

I was trying to save positions of duplicated mc’s. Because after some movement the dup. mc’s have to return to it’s original x&y pos.

But I was wondering what is more efficient or better to do:
create two arrays one for x and one for y?

0001000
0010100
0100010
1000001

would become:
titlex[4,3,5,2,6,1,7]
titley[1,2,2,3,3,4,4]

Or create a multidimensional array

0001000
0010100
0100010
1000001

And that’s also the part I don’t understand yet…
[0001000]
[0010100]
[0100010]
[1000001]

So this is the result using only two arrays

(named “Return to your place”)

But could someone give me his or hers thoughts about the multidimensional array?
Perhaps how it would be done?
I read sen’s article about isometric’s and he was using it but I think what I would to create is a little bit different.
