Could you please clarify for me what the reference to the number 65536 that
is part of the function does and why that particular number?
Is that how many rows a spreadsheet can hold?

Yes, it's the total number of rows a spreadsheet can hold. That number
was used so that the dynamic range would extend all the way down to the
end of the spreadsheet. One can always reduce the range by changing
that number.

And again for the reference to (9.99999999999999 and 307?
What is the purpose and role of these numbers in the overall reference?

It's the largest number that Excel recognizes. In this case, it's used
as a lookup value for the MATCH function. It returns the position of
the last numerical value in the range of cells specified in the MATCH
function.

Hope this helps!
