Data is both read from the offline map and from the live map and the changes in the live map are merged or overlaid with the offline map, where 99% of the data still comes from the offline map. (I do not exactly know how it is merged/overlaid) That is of course much faster with a 300MB (partial) map than with a 2GB map, even though the data is indexed.
At first I didn't like the partial maps as you needed to download a lot more maps instead of one, but "normal" rendering (without live maps) has also improved due to this.
