overlapping of rules? - Palestine

The current rules may capture the Palestinian reality--a regular DST end date was established in 2009 (applying from "2009" to "max") with a one-time exception this year ("2010 only").
(Note that the time zone compiler notices that nothing changes on the first Friday of September, 2010 and does not produce any "extra" output.)

Subject: overlapping of rules? - Palestine
Hello!
Currently the rules for Palestine are:
Rule Palestine 2010 max - Mar lastSat 0:01 1:00 S
Rule Palestine 2009 max - Sep Fri>=1 2:00 0 -
Rule Palestine 2010 only - Aug 11 0:00 0 -
The first line is fine, this is the start-date and says it's in effect from 2010 going forward.
The last two lines appear to overlap. The second line says the end-date is the first Friday in Sept starting in 2009 going forward (including 2010). The last line says in 2010 the end-date is Aug 11. I do see that Alexander Krivenyshev (2010-07-20)pointed out the "Clocks to go back during Ramadan--and then forward again"
I believe this Aug 11 end-date is a one-time exception. So, does the following make sense, to avoid the overlapping rules for the end date?
Rule Palestine 2010 max - Mar lastSat 0:01 1:00 S
Rule Palestine 2009 only - Sep Fri>=1 2:00 0 -
Rule Palestine 2010 only - Aug 11 0:00 0 -
Rule Palestine 2011 max - Sep Fri>=1 2:00 0 -
Would this not be more acceptable? I have yet to encounter any overlapping of rules previous to this one. Am I missing something?
Thank you for your time!
