I can say the same for Egyptians, Labanese, Fillipinos, South Africans too...I mean first attend to their folks and then anyone else. But I take it as a natural instict being comfortable or rather cos one can relate to another being away from home, you understand what I mean..:). So dont see any harm. BTW my personal experience with people from Kerala is altogether different...they tend to attend to non Indians ahead of Indians or may be it is just me being from North India...cant say for sure...:)
