The X5200W was a better built model with stronger amps, more features, and also mfr'd in Japan like the "flagship" models (as are the current 6000 models that replaced the X5200W).
let's not fight about minor details.
Denon and Marantz never declared which models are sisters and which are not. The 5200 doesn't fit into the naming/counting convention anyway. Based on the release date and feature set it should have been a 5100 (never released).
5200 and 7009 share the same features (i don't care about 4+1 composite and "only" 2 component video inputs at the 5200 compared to 3+1 composite but 3 component at the 7009)!
the 4200 can't be the sister since at came a year later, we need to look at the 4100 but that had just 9.1 pre-processing, even with external amps you can't run a 7.2.4 system like with 5200/7009. For me(!) 7009 and 5200 are the "sisters" since there is no other Denon model comparable to the 7009 and the 5200 has no additional features (i don't count 0.5dB more power also).
nevertheless, the real point is: D&M tried to place Marantz as a kind of "underdog" that days, obviously it worked
they didn't want the "small" SR7009 (though it was the AVR flagship) to be perceived "as good as Denon". Marantz is so proud of their HDAM but the word "HDAM" doesn't show up in any official announcement or press release for the 7009. You have to manually search for it within the technical specification and find a checkmark or yes. Then look at the AV7702 Pre, from the feature set exactly the same as the 7009 but without power amps and guess what? There the HDAM parts are highlighted several times even with an extra section within the product description.
THAT's the point! Simple marketing tricks...
