Ursäkta för min dåliga Svenskan!
Perhaps you misunderstand my communication with CT. We're not discussing geo-radars and scanners, but what one may and may not interpret from their pics.
If you think that a certain structure is enough to prove anything about the customs of the people that built it you're indeed out on a limb. When Maxwell Cade made his "Radio-Detection-And-Range-device" he were able to detect airplanes crossing the English Channel long before anyone could see them or hear their engines. But he could still not tell what the pilots had had for breakfast - even though he knew that a certain percentage would have had sauerkraut. Mixing building-structures with sauerkraut you can use any razorblade any way you want - and still don't make sense.
Your links tell about two long-barrows found in England that's quite out of the ordinary, where missing bones still makes a puzzle. Thus the de-fleshing is one of more possible theories.
As you may know we have thousands of long-barrows (trapezoid tumuli) across northern Eurasia - from Ireland to Kaukasus. The general use of these structures are still upp for discussion - but it's quite clear that many of them were something different than graves. Perhaps Hodder was rigth claiming that barrows with chambers resembled old long-houses - built as special (cultural/ritual) meeting-spots?
Made in an age where the overwhelming majority of peolpe got cremated, it's difficult to explain the enormous work made to create these monuments unless they were of some practical value to their builders.
Archaeologists including Ian Hodder have noted similarities between the two forms although a significant number of long mounds in southern England have been demonstrated more recently to have limited primary evidence of burial at all.
Traditionally, these structures have been interpreted as 'houses' for the dead and that barrow builders may have continued this old idea in the Neolithic and later periods. In those long barrows that do contain appreciable quantities of human remains, their concentration in just one small part of the overall structure has led some to argue that the long barrow was not merely a repository for the dead but also a general monument acting as a territorial marker, a place of religious offering and a community centre. Some appear to have been built over pre-existing occupation sites which may support this interpretation.

Obviously we have to wait untill the building is excavated and analyzed, before we may get a substantiated and qualified opinion about the use and re-use of this one, too.
