I don't think they say Oswald said he was alone.
FBI agent James Bookhout, wrote:
"OSWALD stated that on November 22, 1963, he had eaten lunch in the lunch room at the Texas School Book Depository, alone, but recalled possibly two Negro employees walking through the room during this period. He stated possibly one of these employees was called ‘Junior’ and the other was a short individual whose name he could not recall but whom he would be able to recognize." (WR, p.622)
Secret Service agent Thomas Kelley wrote:
"He said he ate his lunch with the colored boys who worked with him. He described one of them as ‘Junior’, a colored boy, and the other was a little short negro boy." (WR, p.626)
What Fritz wrote: "say two negr. came in. One Jr. + short negro" refers to what Bookhout and Kelley wrote. There's nothing in all these accounts about Jarman and Norman entering the building through the back door.

Kelley wasn't there at the first interrogation, so he couldn't have heard Lee's statements....

Lee told the interrogators that he had eaten lunch in the lunch room at the Texas School Book Depository,
alone, He recalled possibly two Negro employees
walking through the room during this period.
This is written by someone (Bookhout) who was unfamiliar with the 1st floor lunchroom, because it is impossible to "walk through" (transit) the lunchroom, because there is only one entrance / exit door.
Lee said that he saw Jarman and Norman come into the building and walk to the west elevator. We know this is true because both Jarman and Norman said that they walked up the Houston street steps, and across the loading dock, and then entered the building by the back door.
You've omitted Hosty, and inserted Kelley, but Kelly wasn't present at the interrogation on 11/22/63 at 3:15 pm. and Hosty said that
What's so difficult about understanding Lee's simple reply to Fritz that he was eating lunch alone in the first floor lunchroom when he saw Junior Jarman and Harold Norman come into the building by the back door. Both Jarman and Norman testified that they did in fact enter the TSBD by the back door at about 12:27.
