GR,

It's not that uncommon that a MACR doesn't say the exact location that's known to us now.
The location was given as best knowledge or recollection one had of the moments when it all happened. Perhaps the pilots reporting at base had had other worries at hand, like engaging German fighters or dodging Flak.
In many cases a better description of the location could only established after the war.
A MACR therefore is a good starting point when and where the missing aircraft was last seen and/or when the last was heard of the pilot.
Given the similarity of the estuaries in Zeeland province, one could easily be mistaken from above what waters one flew over.

Groet,

Leendert
