What's curious is that there aren't many duelling rides that rely solely on a control system to ensure that they don't meet/collide - it's usually that they operate closely to one another but their paths are forced to be independent of each other (think of something like Vertigo at Tivoli, for example).
From the sped up footage, it appears that if one of them stopped and the other continued .... well, that would be sub optimal.
It looks like that, but I don't think there's any point they could actually meet, presuming the end stop where they nearly touch is a physical limit the cannot be exceeded.
