High altitude ABM that can intercept IRBM can also intercept satellite on orbit as high as hgesht possible apogee that rocket can achieve. long range BM are difficult to intercept primarily because reaction time to determine its trajectory with sufficient accuracy and have the interceptor travel that distance in available time is the bottleneck. With satellites that is not a problem, ABM has litrally all the time in the world against a tagret that slowley and predictably (apart from presenting itself periodically for re-targeting) . In fact in such case it can simply launch the intercpetor in intended kill box and after a long coast to upto the apogee the intercpetor thurstrs will take care any residual inaccuracy.
The ASAT mission is not akin to Hbomb, it is akin to BM test. Once you have tested BM's final velocity and velocity trimming package in conjunction with navigation and guidence, the missile system has confidence to take on all possible range with the rocket motor's capabelity. Same is true for ABM systems.
Testing a high lobbed IRBM target is sufficient to demonstrate deterrence against Satellites too.

Thanks for the explanation, which begs the question what can Indian do to prevent its satellite from similar threat , since China has already demonstrated ASAT capability against sats in Polar/Circular orbit.
