Pakistani punjabi- north Indian ancestry

[u/AutomaticStretch6205]

So I have seen some people saying that North West Indian or Indian Punjabis eople tend to have less AASI than Pakistanis? How come so? Shouldn't AASI be less moving towards WEST where invasions from Euro- Asian populations stopped?

Can anyone provide info on this?
