Bro according to what I've seen on my bike (I think it is typical to your too) and on my diagram.
Yellow/Red - Power supply coming from stator/rectifier
Blue - For Auxiliary/ Park Light
Blue/Black - from Head light switch going to your Hi/Lo switch
On the Hi/Lo HID, the trigger should be on the Hi/Lo switch.. Actually the Hi/lo HID kit is just plug and play..
The red and black (with fuse) are to be tapped to the battery terminals.. Red (Positive) & Black (Negative)
The other two wires of your HID kit (blue and white) are for the High beam and low beam respectively..
Tap the blue wire of your HID kit to the yellow (HI) of your bikes Hi/Lo switch and the white to the green (LOW)..
You're understanding is correct..
HTH
im just not good in this electrical wirings.. but my mechanic did cut the yellow wire in the rectifier and my parklyt was always getting busted then after a month or two my HID was installed, my battery always drains.. i charged it til 11.8V then after a week it was already drain then i charged again and got drained again in less than a week.. i changed my mechanic and he said that the earlier mechanic didnt cut a wire.. i think its the yellow wire connecting to the stator (i think).. then he said my lights would get busted if that wire wasnt cut.. my friend then said it wont get drain again but if it does, maybe there's something wrong with my battery.. after 3days my battery got drained again
