Disable address

Questions regarding ‘Add Listing Form Settings’ under Multilocations.

I’ve attached a screenshot of the two settings I’m curious about.

-Disable set address on map from changing address fields
-Disable move map pin from changing address fields.

1) Says ‘Useful if you have a small directory’ – what do you consider a ‘small’ directory that can use this function? Because I am using GD in an unusual way to list trails and other natural features, most don’t have a street address and Google pulls an address from a far away city, which is confusing.

3) Says ‘Highly recommended not to enable this.’ When would this be recommended?

Please advise.

Thanks!
