You don't understand because you have no experience with them.
AK, FD etc is a point to point operator. Segment by segment. No through check of bags. 1 flight check in at a time. Another poster mentioned through check for flight to Perth, but I'm not privy to any through-check in SE Asia.
OP will need to exit immigration, collect bags, go through customs and re-check-in on Level 4. If OP is traveling on an India passport they will also need to apply for a visa on arrival in BKK before they can do any of the above. Thus 125 minutes is not giving alot of time for any problems/hassles.
