Confusing mission issue description

I would like to give some feedback about the confusing mission issue description in https://py.checkio.org/en/mission/sort-array-by-element-frequency/.

The issue was described as "If two elements have the same frequency, they should end up in the same order as the first appearance in the iterable.". Here I have an example just as the test case [4, 6, 2, 2, 6, 4, 4, 4], while in my opinion [6, 2, 2, 6] is the first appearance in the iterable not [6, 6, 2, 2].

Have I understood correctly?
