Two problems here:

* The Interleave controller is intended for use with Samplers, or
samplers nested in other controllers. Ultimately there must be a
sampler to execute. When a sampler is found, the other elements are
processed as follows:

http://jakarta.apache.org/jmeter/usermanual/test_plan.html#executionorder

* UDVs are processed according to the level in the tree, not the position:

http://jakarta.apache.org/jmeter/usermanual/build-test-plan.html#scoping_rules

One possible way to do the same would be to use a CSV DataSet with
four lines, each with two columns for the index and area variables.

The manual could be clearer on this ...
