Galactic Unicorn has unusual pullup resistors

I was browsing the schematic for the Galactic Unicorn and noticed it has two pullup resistors on LA_CTRL_2_3V and LA_CTRL_3_3V. Given there are four lines that all look the same it seems odd to have pullups on only half of them?

I also note they are not present on the Stellar and Cosmic. Those do have a pullup on LED_BLANK which is not present on the Galactic.

What’s the reason for the difference? I’ve not noticed any issue from any of this.
