I look through GLX manaul and found RIN an GLX function is exactly same, I am wondering why allen bradley developed 2 same function instructions ,

You are right RIN and ESTOP are the same instruction.

You can use these 2 instruction's to indicate different things inside your code. ESTOP to perform an emergency stop, RIN for zoning from a switch / light curtain for example.

I think these were made available with different names just to make it easier to program and understand your code.
