I would think they're very much alive, but as far as "well" is concerned, idk. Maybe they are "well", maybe they aren't.
Particularly if they've not bloomed at all for Rosie.

Rosie mentioned the flowers on Pleiones last for about a week. I tend to agree.
Most orchid genera I've grown have flowers that last in that timeframe.

It depends on the orchid. Some Phals and quite a few Dendrobiums have flowers that last up to 3 weeks or more.
Some Catts also have flowers that last up to 2 - 3 weeks.
Some orchids have flowers that are ephemeral and last only 1 day or less! Orchids in the genus Flickingeria and most species of orchids in the genus Diplocaulobium are like this.

Keeping the Pleiones cool will keep the flowers longer only by days, not weeks.

I've found this to be particularly useful with terrestrial orchids in general.
A lot of terrestrial orchids in my experience tend to respond much more favorably in conditions and soils that are much closer to what they'd encounter in the wild.
I think one of the issues regarding potting mixes is that they must reflect the pH of the soil the terrestrial orchids originally came from.
For example, Cypripedium acaule is an orchid that was known to be notoriously difficult to grow, not because the species is a problematic species. It's because even if people were able to provide the cool temperatures needed to grow this species of Cypripedium, most people were not aware of the fact that they grow in bogs and like peaty and very acidic soils.
In the case of Pleione maculata, it would seem likely that the pH of the soil needs to be more alkaline because of the limestone.
I also think that one of the nutrients Pleione maculata utilizes to function properly is calcium.

Ok, cool.
