Here my code goes:

                            $this->SetY(0.208333);
                        }
                function Footer() {
                                 if ($this->footer <> 1)
                                 {
                                $this->SetY(-15);
                             }

I didn’t follow the code completely, but it seems you’re using the Header and Footer methods to set Y and nothing more, expecting that to be enough to correctly position the MultiCells being output outside of the Header and Footer. Maybe so, but the interaction of positioning inside and outside the Header/Footer isn’t well defined.

For example, the process may be something like this: Y is calculated for the MultiCell, that trips the footer, the footer changes Y, the MultiCell is output. Is this the original Y, the revised (by the footer Y), or some other value? Absent a precise definition of what happens, you’ve set up a complex sequence of things that would be very difficult to sort out.

I would suggest vastly simplifying the code. You may find that the automatic header/footer tripping isn’t helpful at all. In that case, turn off the auto page break, get rid of the Footer/Header functions, and totally control each page yourself. That way at least you have a clear, reliable model of what’s going on.
