Thrust = MV. I'll see if I can find page references for you.
EDIT: Perhaps you've uncovered something that should be clarified via erratum. I don't see it ever explicitly saying thrust is just another way of saying MV. But, it is.
If you don't want to take my word for it, you can get an official answer from the rules guys in the rules thread.
EDIT2: I did found a quote that does indirectly imply thrust = MV, since AS cards put movement mode codes next to MV values:
Hovering in Place
Any aerospace unit with the Airship (i) or Spheroid (m) movement
mode codes beside its Thrust rating may hover in place during the
Movement Phase. Hovering allows the unit to remain in its current
zone, rather than move out of its current region.
Underlined for emphasis.
