Indians culturally have a 'do the needful' mentality ingrained into them, which in most workplaces translates to just working as fast as possible to look good, and not thinking about anything or paying attention to detail. If you have ever worked with Indians you will know this to be true, they intentionally go out of their way to work their ass off to look like amazing workers, but also make a bunch of mistakes because they are speeding through everything without much care. Quantity over quality manifest. In this instance I suspect someone may have raised a concern about this and they just fobbed it off and got the flight out on time because at the end of the day that's what looks good in their numbers. In most workplaces this is harmless other than an effect on quality, but I suppose in aviation it could be quite dangerous
