2 Asian men stalked me from Kelenfold bus platform to the metro vehicle - part 2

And they are taking the same metro to Kileti direction from the bus station. If they were not waiting for the bus, their just purchasing the ticket behind of me to the metro ride would look normal. But why they had to wait for the bus to Vienna Airport? I'm heading to Vienna for the possible long term staying and suing Druck Box copy store for the antisemitism there.
