Issue with altitudes in KMZ flight path data at landing



We have been examining the KMZ flight path data for flights into HKG airport and note that after landing the z-values remain significantly above the ground

e.g. for flight CES2901:
gx:coord113.93 22.321 152</gx:coord>
gx:coord113.918 22.318 152</gx:coord>

Any clues on this?
