Anyone else catch the Residual Haunting reference in Part 4?

When the UP heritage units are meeting to discuss Misty's disappearance (it's almost a literal vanish without a trace, as UP #1995 mentions that UP officials were unable to locate her on the tracker; indicating that her kidnappers disabled her tracking device), Eddy says "Perhaps Misty was kidnapped by a ghost steamer and vanished into the unknown".

The bridge in that fantasy is the same one as in Residual Haunting, and the FEF-3 was also numbered 836.

What makes it more like Residual Haunting is that the other heritage units, Mark in particular, didn't believe Eddy. The only difference is that in RH, Eddy was telling the truth about the ghost, but the others didn't believe him, while in the ROHV episode, Eddy's statement was merely a conspiracy theory.
