I've had Indian managers and never experienced this. You're probably extrapolating from a small sample size which may all be from same company / industry.
I have had 7 managers from India at big US companies over a 30 year span and 6 of them where like this. It is an interesting phenomenon, in another timeline I'd like to be a tech ethnographer.
Most people who have worked both in the west as well as in the country will say there is a stark difference in the superior-subordinate dynamic between these two places. Concepts of professional respect, upward feedback and personal boundaries are less evolved here. It's a byproduct of the region's culture which is inherently hierarchical. While there are places which actively eschew traditional ways, especially those that are part of global orgranizations, given the size of the industry there are many more where a strong hierarchy and subordination is unfortunately the norm.
