This is extremely complicated, hard to understand and hard to maintain. For all practical purposes this functionality is in efect not supported. Really, this looks more like a bad joke than anything else.

I feel concerned that this approach is not working for you. At this moment, event data of the RowValidating event does not contain values from template editors. So this solution is the only available way to use this event with the Edit Form template. If you face difficulties with this code, feel free to submit a ticket describing your scenario in greater detail. We may be able to suggest a workaround for your case.
