The 1949 Armistice Agreement between Israel and Jordan was specifically written as a ceasefire agreement, and not a final peace treaty. It was specifically written to designate the boundary of the ceasefire to delineate ONLY the exact area (on a map, with a green marker) where the Israeli army and the Jordanian army had advanced and were currently located.
Article II.1
The principle-that no military or political advantage should be gained under the truce ordered by the Security Council is recognized;
Article II.2
It is also recognized that no provision of this Agreement shall in anyway prejudice the rights, claims and positions of either Party hereto in the ultimate peaceful settlement of the Palestine question, the provisions of-this Agreement being dictated exclusively by military considerations.
Article IV.2
The basic purpose of the Armistice Demarcation Lines is to delineate the lines beyond which the armed forces of the respective Parties shall not move.
There is no border. There never has been. It was specifically written to ensure that the 1949 Armistice lines could NOT be used as a present or future border. It would be the same as saying that the border between Israel and Gaza now lies south of Gaza City, because that is where the recent ceasefire lines were drawn.
It is not occupied territory. There is a mutual agreement between the State of Israel and the State of Palestine about how those territories are to be administered, pending the emergence of a self-governed State of Palestine and a treaty of peace, which will determine the borders, disposition of Jerusalem, return of displaced people, among other significant issues. That territory is provisionally, and temporarily, and voluntarily placed under the authority of the government of Palestine. But that territory has NOT been ceded and without a permanent peace agreement solving the above issues, the territory remains under Israeli sovereignty.

Article XXXI.6
Nothing in this Agreement shall prejudice or preempt the outcome of the negotiations on the permanent status to be conducted pursuant to the DOP. Neither Party shall be deemed, by virtue of having entered into this Agreement, to have renounced or waived any of its existing rights, claims or positions.
