Not quite, there is a difference between actions on events and actions on the
default node type. If you do the latter, you create a new custom node type. In
that case the actions are indeed responsible for propagating the execution.
Actions on events (like task-end) should not influence the flow of te process.
That is what these lines in the documentation mean.

You could do this, if it is an action on a node, not an action on an event. But
then, you could not use the task node for this and get all the advantages of
the tasknode

Yes it does, but you mixed to concepts. What you could do is just have a task
node with one transition (like finish) and a decision node below that which has
an action to decide which transition to take (decision nodes are the exception
to the rule that actions on events should not influence the flow)
