I asked because I was concerned like you about overfilling & blowing a hose , but thinking about it the worst that could happen would be the overflow bottle filling & overflowing.
As it is I think I'm just observing the coolant system 'settling down', purging air from the system resulting in the 'pressure bottle' level dropping. Have now topped it up to look like yours (without the nice clean & new appearance of course).
