That's not entirely clear. They appear to have some concern that tunneling, well below these properties, may result in cracking of foundations/structural damage.
Certainly, if that is the case, they would be on the hook; and if the risk were significant enough that there was any risk of structural collapse of buildings (or a gas explosion), then the current residents have to move out, at least temporarily.
Of course, neither the residents, nor the public seem to have seen the geological testing results that indicate a danger, and the degree of risk.
Mx staff also appear to have told residents that their properties will be resold after the O/L is complete. This would seem to suggest a fairly low risk in the mind of Mx; and those same staffers indicated Mx would sell at market price, so existing residents could not buy back at what they were paid, or the same indexed to inflation.
The optics make this look a bit like a money-making ploy; which I could arguably get behind, but I'd want to see transparency around that.

From the description, these appear to be the properties in question (aerial):

Note the proximity to the new O/L Station would allow for this to be considered an MTSA, and fully assembled, the total area works for an intensified development, albeit backing on to SFH.
The lots are very shallow though, and would not be conducive to a conventional tower. This would either go midrise, or slab-style, which, because its orientation would be N-S would be acceptable in my judgement, though I doubt the locals would agree.
Of course, they could just buy the homes on Poucher (the other side of the laneway, and then comprehensively re-do the block, which would be easier.
