FollowTrajectoryAction: closed flag interaction with an initialDistanceOffset

Problem:

Please clarify how the closed flag interacts with an initialDistanceOffset in a FollowTrajectoryAction. Unfortunately, it looks like the description in the model and the structure are contradictory to each other as the model states:

A FollowTrajectoryAction with a closed trajectory doesn't end regularly but has to be stopped

but on the other hand, the initialDistanceOffset is described as

logically truncating the trajectory

This would mean that the trajectory is not closed anymore.

Supposed Solution:

For the general use case, it would be reasonable to let the trajectory start at the initialDistanceOffset without truncating the trajectory if it is closed. Therefore, the trajectory is closed regarding of the initialDistanceOffset. Please specify this in the model.

Thank you in Advance!
