It could also be a reflection of how laptop usage has changed over time. Maybe a couple of years ago laptops were closed most of the time, hence the decision to put the logo up that way.
In the future, they should create the microholes and keep the logo dimly lit in the orientation that faces the user when they open the laptop. Once the laptop is open, the array of LEDs could change to make the logo oriented the current way.
There is already something similar on one of the numerous android handsets out there where the 4 hardware keys turn 90 degrees when you switch from portrait to landscape mode. Not quite as polished, but similar in concept.
The lit-up logo is Not powered by a special array of LEDs, it's just the screen backlighting shining through a hole.
You can verify that by changing the display brightness, the logo will change brightness accordingly. Or just hold the turned-off laptop in front of a bright light source, the apple-shaped hole wil, be visible through the screen
It still took them a while to put them on the right way up. The first few laptops they sold with the Apple logo on the lid, they were oriented so they were "right way up" for the user when the lid was closed. That made them all upside down in all those tech conference shots from the stage...
