Yes, but take care, two strings in a non freed object (in example)
will produce three memory blocks. 1 for the object and one for each

Where it has been allocated or reallocated (it could be used somehow
later, or never).

To follow the sequence yes.

You may allocate a memory block in the same line following different
paths, finally all memory blocks are a "GetMem" so if only one line is
quoted you will only see "GetMem" procedure.
