I don't get people like you - you are seriously contemplating what Putin's PR team announce on given day as some seriously meant opinion that's worth anything. When its exactly opposite, just empty words, full of lies, deceit and lack of anything meaningful. Spending any amount of energy on them is waste of time, next day will next round of demands.
You do realize that even if his demands would be met for some reason, there would be another and another round of demands till you have nothing and he has everything. Just random things I recall were mentioned by him/PR in last month - complete demilitarization of Ukraine (so you can defeat whole country with 2 tanks), demilitarization of whole Europe (hinting at his long-term ambitions).
Everybody in politics recognizes this and realizes that peace talks are sham, yet another set of lies. War will end exactly and only when he decides it, not a second earlier regardless of whats happening in Ukraine and rest of the world.
