Final destination

Some few hundred posts ago….some said the AP would result in a descent rate of 300fpm to maintain flight until it gave up.
Don’t recall IMMarsat giving details of altitude of pings, simply distance. IF already taken into account, please delete this post and would be grateful for link.
Questions:
1 Given the shape of earth, it would depend on the altitude and distance of a/c to be able to talk to satellite, which means there is a minimum and a maximum altitude for satellite horizon areas, according to the distance. True?
2 If true, then would this not change the projected line of flight -from point of fuel exhaustion and altitude (PFEA) into a much broader lane? If true, then
a) how long would it take a/c to touch sea level after George has done his job, taking into account possible altitudes (max to min)?
b) what would be the maximum possible lateral deviation of a/c from PFEA to sea level, taking into account one engine running on air before the other (which means the lane gets broader still)?
