I think information is correct.
Train belongs to WR & hence Coach Position in Rake will favor the same (Ascending Order). If not altered at Secondary Base or reversed in between, all trains returning back to Home Base do have reverse position (Descending Order).
EG:
1. BSB GR- @ ANVT, Coach starts as G-15 from Loco (Base-BSB).
2....
more... 2392 Shramjeevi: @ NDLS, Coach starts with S12, while 2391 starts with S-1 (Base-RJD).
3. Kushinagar Exp: UP & DN have Ascending Serial, must be altered @ GKP
4. HWH-CSTM Mail (via ALD) have Ascending Serial from HWH & CSTM because of reversal @ ALD & alteration @ CSTM.
etc.
