Check out the difference in how the SU-30 of the Indian airforce and F-16 belonging to the Pakistan airforce perform the same maneuver during their respective day occasion. The IAF uses it's SU-30s in what it calls vertical Charlie while PAF calls them Vertical Rolls.

I think you have made the wrong conclusion here. SU30 with its twin engine and thrust vectoring technology can run circles around F16. Not vice versa. You can see WVR fight enactment between the two on DCS simulation videos online. I think what IAF with its SU30 is trying to show is the low stall speed of SU30 MKI. They are showing that the aircraft has a thrust so high that it does not need momentum & inertia to perform such an aggressive maneuverer. If the same was tried on an F16 at same speeds, it would just fall out of the sky. SU30 has more than double the thrust of F16. There is no comparison between nose authority of an SU30 MKI vs F16. SU30 can point its nose at F16 at anytime at wish and command.
123 KN x 2 = 246KiloNewton vs 106KiloNewton of PAF PW powered F16s.
The following video is of a SU35 I know its better than SU30MKI. But of the same family. Results wont be much different with SU30. F16 would struggle to keep up. Not saying it can't be done. But advantage is with SUs.
And what happens when JF17 goes WVR with SU30MKI
