I still use this feature all the time (we live in a rural area with many pockets of no reception). Yes, it will still try to fetch live data if you have a connection, but if you're out of LTE/5G range it won't. Or you can just turn on airplane mode and it'll always use the offline data. In recent versions, it will also auto-cache tiles along the way if you navigate somewhere far away, even if you don't explicitly tell it to. Both features have saved me from getting lost many times...
