ExecutionId differs for task from taskservice versus historyService

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I get a different executionId for the same task, depending on my type of query.

List<Task> tasks = taskService.createTaskQuery().taskAssignee(userName).list();
//no, that "9" is not hard coded.
tasks.get(9).getId() // 36033
tasks.get(9).getExecutionId // 33107

Task task = historyService.createHistoricTaskInstanceQuery().taskId(36033).singleResult();
task.getExecutionId // 36028
‍‍‍‍‍‍‍‍‍

Activiti Version is 5.16.4, but i think the few task concerned by this where created before we upgraded. The old version was 5.14.
The history-property is not configured, so i guess it's 'audit'.

Is this indented and i have understood something wrong?
Or did i stumple upon a bug or use the Activiti API wrong?

I will happily provide more information if needed, but my understanding so far is, that the executionId should match.

SQL:
<blockcode>
select ID_,EXECUTION_ID_ from act_hi_taskinst where id_ = 36033;
->36033, 36028

select ID_,EXECUTION_ID_ from act_ru_task where id_ = 36033;
-> 36033, 33107
</blockcode>

Typo in Line 6 of my Code, it's obviously
<java>HistoricTaskInstance task = historyService.createHistoricTaskInstanceQuery()…</java>
