'Bucks' they may not have had anything useful set up on their VOR or in fact had the rose display on their ND leaving them with just the head of a VOR needle moving about at the top of the arc display. With a 340 course set which isn't aligned anyway with Rwy 34 anyway wouldn't provide much assistance to them unless they where watching that closely & considering that they 'thought' they had ML in sight any level of dial watching would have gone out the window as the brain once it gets what it 'thinks' is reliable info that's it it's locked on & disregards all other info. You see what you 'want' to see in this case.
The single biggest 'who is minding the shop' issue here is the pictorial view of the selected Rwy on the ND, their current track (towards EN Rwy35) would have had ML's Rwy 34 way off to the left still oriented correctly (well close) in ref to Nth but not aligned with where they where heading, that's their biggest missed cue.
