The original code has a bug.
It's incorrect to compare tle1 and tle2.
If a new tle2 is created, tle1 is destroyed.
It is possible that the Delphi memory manager reuses a freed memory, so tle1 = tle2.

var ItemNoI, ItemNoF, OffsI, OffsF: Integer;
tle1, tle2 ...

For example, if the cells are (2, 2) and (3,3).
Should it clear the cells in the (2, 3) and (3, 2)?
Or should it clear all cels in the row after (2, 2), and all cells in the row before (3, 3)?

This code must do nothing is the words are in different cells.
The check "if tle1=tle2 then" is to ensure that the words are in the same cell.

The code for deleting content between two cells would be much more complicated.
What does "content between cells" mean? If the cells are in different rows ...
