the best way to understand the language in the ruling, and why the philpot-jwr legislation was so inhumane and flat out terrible, is to ask yourself the following question:

if you suffer from a "grievous and irremediable medical condition", is your suffering likely to be greater or lesser if you can't demonstrate that your death is reasonably foreseeable?

it is the people that can't demonstrate the imminence of their death that are precisely those that need assisted suicide the most!

if you reduce the legislation to saving a few bucks in avoiding keeping people alive longer than necessary, which is essentially what they did, you're essentially putting aside the ruling; you're missing the point.
