Either flat out incorrect or contraindicated by the Apollo 11 Voice Transcript
Apollo 11 Mission report section 11-6:
"11.1.3 Analysis of Transmitted Geologic Data
Location of the landing site.- The landing site was tentatively identified
during the lunar surface stay on the basis of observations transmitted
by the crew.
...
A description by the Commander of a double
crater about 6 to 12 meters in size and south of the lunar module shadow
plus the identification of West crater, the hill to the west, and the 21-
to 24-meter crater reported behind the lunar module, formed a unique pattern
from which the landing site was determined to within about 8 meters.
...
The returned sequence-camera descent photography
confirmed the landing point location. The position corresponds to coordinates
0 degree 41 minutes 15 seconds north latitude and 23 degrees
26 minutes 0 second east longitude."
(My highlighting.) Back to square one, it appears.
This is from "day 6" of the Voice Transcript. The astronauts are traveling toward the earth and are days from splashdown. The landing is long behind them and neither the astronauts, nor the Houston staff know where the landing site is located. As a matter of fact, it is the "64 thousand dollar question".

CC: Roger. For 64 thousand dollars, we're still trying to work out the location of your landing site, Tranquility Base. We think it is located on LAM-2 chart at Juliet 0.5 and 7.8. Do you still have those charts on board? Over.
Armstrong: Yes. Stand by one. They're packed.
CC: Roger. You may not have to unpack it. The position which I just gave you is slightly westof West Crater. I guess it's about two-tenths
of a kilometer west of it, and we were wondering if Neil or Buzz had observed any additional land marks during descent, lunar stay, or ascent which would confirm or disprove this. One thing that we're wondering about is that if you were at this position, you would have seen the Cat's Paw during ascent just up to the north of your track. Over.
Armstrong: We were looking for the Cat's Paw, too, thinking we were probably downrange, beyond the Big V.
But I think that it's likely that that might have been West Crater that we went across in landing, but - Stand by.
Armstrong: We're hoping, Bruce, that our 16-mm film was working at that point in descent, and we'll be able to confirm our touchdown position. We thought that during ascent we might be able to pick up some recognizable objects close to the landing site, and we did see a number of small craters, and crater rows, and things like that, which we may be able to pick out after the fact, but we haven't been able to yet.
