I bet they'd say, to a man, that that's the way they were taught

If you watch normal British-food chefs on TV, sometimes the explanations for techniques they use are completely wrong (and different each time one of them tries to explain it). They often resort to folklore-ish explanations.
Meat is a prime example. Some say sealing prevents loss of the juices, whilst others state that this is complete rubbish. Tests show that it IS complete rubbish, but most still do it citing that explanation.
And seasoning meat is another one. Some say season before cooking, and others say do it after because it will cause juices to be lost. Personally, I've found seasoning before cooking gives a better flavour (British dishes, here) and doesn't cause it to suddenly turn into powder

but if I forget it hardly matters.
I can't see Indian chefs being any different really
