I would say it's an unlikely coincidence, but not truly bizarre.
- It's common for desi names to start with A or K
- It's common for desis to use initials when referring to themselves
- Some desi surnames are over-represented in the population
- People with desi names are likely to come in contact with South Asian culture irrespective of their environment or if they speak the relevant languages. Or rather, they are more likely to have these avenues to begin with if they ended up with such a naming scheme.
- There are only so many foundational or well-known texts in any culture, so if there is a relevant passage, it has a high likelihood of being cited
It's not that different from a Jay Smith and a John Smith quoting a relevant C.S. Lewis or Biblical passage and having a jsmith handle.
