If you now uninstall program A, the uninstaller cannot uninstall .dlls a1, a2 and a3 because it does not know which other programs might be using those .dlls (in our case program B using .dll a2). So to be on the safe side, all .dlls that are in the system remain in the system - regardless whether the original source programs are still present or not.
thanks, so there is multiple program or not just one or previous program that using the .dlls (the one that abruptly exist)? am i right?

ermm, i mean for the .dlls data, not only 1 program/software that make it exist using it right? even the previous installed program/software just make the .dlls exist, but after uninstall the program, the .dlls will still used by another program. am i clear?

Yes, that's correct. Multiple programs may use a .dll, regardless of which program originally installed it.
