I have no idea why that would be a sequence point. Taking the
output conversions, my guess would be so that something like
%n can function. Am I right, my dear audience of 1 or 2 people?

This sequence point is there to allow you to use code like
double d;
scanf("%lf %lf", &d, &d);
without worrying about the inner workings of 'scanf' violating the
requirements of 5/4 in this case, i.e. worrying about whether internally
'scanf' will attempt to modify 'd' twice without an intervening sequence
point or not.
