What is confusing? According to an interview in 1UP, Emil was asked if Liberty Prime was an intentional reference to Optimus Prime and he said no.

What about it?

Transformers showed up in the mid-80s. They were really popular at various times. Optimus Prime, Liberty Prime. Understandable question.

Prime is a military term for main or primary platform. Prime Mover for example is used on a vehicle that is capable of and used for towing anything the army has.
