Two, the perspective of the manual is seemingly from an "ominiscient narrator" whilst the Overlord exerpt is a personal/subjective recollection. We have no reason to doubt the veracity of the information from the manual at the time (until a later retcon proves otherwise - which is what point one is about), whilst the Overlords are giving their potentially skewed interpretation of past events. The "psychic beacon" the Overmind sent out may still have been the initial inciting cause for the Gargantis to know of the existence of the Zerg before they then called to the Zerg themselves (also, the "psychic beacon" need no further explanation of its origin beyond the fact that the Overmind was just reaching out it with its senses). Third, the Overlords words are hardly specific or exact in terms of the when, what and how of things.
And yeah sure, it can align with your theory but not mutually exclusively to anything else. In fact, it still doesn't resolve the original and apparent plot hole/inconsistency of why the Overmind still didn't have any means to get off Zerus until those space faring gargantuan life-forms appeared when it supposedly had a means already through their early and initial assimilation of space-faring Gargantis (irrespective of its actual functional efficiency/utility). Your theory requires more and more fanon to justify it whilst mine requires comparatively little. It also doesn't clarify why one should expect "space-faring" for the Gargantis/Overlord entry to mean "hitching a ride on actual self-propelled space-faring creatures" whilst one should simultaneously expect it to mean self-propelled space-flight for those gargantuan life-forms described in the history.
