Correct - the assumptions here are the people have not met in person (even if they've talked, FaceTimed, what have you). We can also assume, however, that this is not a situation where one person assumes this is a date while the other person assumes it's just a couple of people hanging out for lack of anything better to do. Most of us have no desire to experience that stomach drop sensation as we ride the Friendship Zone Tower of Uncertainty.
If you've talked a good bit, facetimed to know they are know they claim to be, and you enjoy each other, you should be ok, especially because there doesn't seem to be uncertainly regarding the terms of the meeting - if its a date or not. Chemistry is unknowable to an existent, but at some point, its degrees of attraction.
