They are.

Because that is not what you are doing.

Reserves room on the stack for 4 pointers.

Sets the first pointer to point to a literal string stored somewhere
in the program.

Changes the first character of the literal string stored somewhere in
the program.

You seem to think that
>char* MyText[4] = {"2 Line Version: Line 1"};
copies the  string, but where would it copy it to?
MyText is only pointers.

You might try this instead:
char  MyText[2][32] =
 {"2 Line Version: Line 1",
   "2 Line Version: Line 2"};
As now, the strings are copied to the stack.
