[JS CS3] Trouble with changeGrep() array

Question

This is strange, or else I'm totally missing something simple:
My script does a GREP search for a text string in a table, and assigns a paragraph style to the string. Next, for each string that was found, I want to merge the cell that contains the string with the two cells directly to the right of the cell. The line
var myFound = mySelection.changeGrep();
does the changing of the text string.
I understand that changeGrep() returns an array, in this case, of insertion points. When I run the script on a table that contains 5 instances of the string that the Grep search is looking for, myFound returns an array of 5 insertion points like I'd expect. Except that if I pause the script and examine the contents of the array, this is what I get:
myFound[0].parent.contents displays the correct (first) text string that was changed
myFound[1].parent.contents isn't correct. It displays the contents of the cell directly to the left of he text string that was changed.
myFound[2] through myFound[4] are also incorrect.
Again, this is examining the array before I do anything to the table such as merging cells, etc.
So, why doesn't the array return the correct insertion points?
Here is the full script function:
function myProcessTable(mySelection) {
// Specify the column width
mySelection.columns.item(0).width = 68;
mySelection.columns.item(1).width = 103.5;
mySelection.columns.item(2).width = 24;
mySelection.columns.item(3).width = 16;
mySelection.columns.item(4).width = 16;
mySelection.columns.item(5).width = 16;
// Find every occurance of ddd.dd/d in the current table, and apply the Table body, cond, center paragraph style,
app.findGrepPreferences = NothingEnum.nothing;
app.changeGrepPreferences = NothingEnum.nothing;
app.findGrepPreferences.findWhat = "\\d.\\d\\d/\\d";
app.changeGrepPreferences.appliedParagraphStyle = app.activeDocument.paragraphStyles.itemByID(locateParagraphStyle("Table body, cond, center"));
var myFound = mySelection.changeGrep();
alert ("Search is completed. " + myFound.length + " replacement(s) made.")
// merge the cell with the two cells to the right
for (i=myFound.length-1; i>=0; i--) { // iterate through each found occurance
var myCell = myFound[i].parent;
var myTable = myCell.parent;
var myRow = myCell.parentRow.index;
var myColumn = myCell.parentColumn.index;
myCell.merge(myTable.rows[myRow].cells[myColumn+2]);

Keith,
changeGrep()'s arrays can't be used for anything, so that's where your script runs into trouble -- it's nothing to do with tables. To work around that, use findGrep()'s array.Immediately before this line:
for (i=myFound.length-1; i>=0; i--) { // iterate through each found occurance
add this one:
var myFound = mySelection.findGrep();
