Airbubba;
...and I'm wondering, if the airplane was actually on the ILS, why does ADS-B data show it so high - or is FR24 data not accurate in altitude?
The altitude is normally uncorrected barometric data from what I've seen although I've heard it claimed that it can be geometric GPS altitude. Some ADS-B viewing software, e.g. RadarBox, lets you set a transition altitude/level and enter an altimeter setting but I don't think the standard FR24 webpage lets you do that.
The position data seems to be spot on in this case and you can see other aircraft back taxi on runway 26 and turn around at the end on the playback so I don't think there is much of a map shift in the FR24/Google Earth depiction.
But, even with an altitude error, it seems odd that the descent continues halfway down the runway in the plot.

Wouldn't the autopilot normally remain engaged for a low-vis go around from a coupled CAT II approach?
Obviously something that wasn't normal happened in this case...
