The top of the H4 9003 bulb activates when the low beam is turned on. This hits the top reflector in the bulb which seems to be angling the light down to the road.

Switching to high beam this bulb keeps the low beam turned on, and keeps the European Parking light turned on, but this time it adds the LEDs from the bottom of the H4 9003 bulb.
These LEDs hit the lower reflector which is angled upwards shining the extra light above the ground splash of low beam light and further down the road.

EDIT: So the alignment tabs just keep numpties from putting the bulb in upside down and have the low beams turn on and hit the lower reflector and shining far down the road.

The low beam on my bike shines about right. But when I put it on high it shines up in the trees. About 11 o’clock. Do you think I should flip the bulb over? Is that possible?
