The sentence says "supported by Japanese SACD manufacturer" (whatever that means!). An example of how the term SACD gets thrown around in cheap domestic and pirated Asian markets (this wasn't a true XRCD either)...
As I mentioned previously in my post on SACD (and DSD), there are a number of SACDs I have digitally ripped over the years that appear to be sourced from 44kHz PCM. This is of course the same sample rate as good ol' RedBook CD and therefore it's unlikely that these titles should sound any "better" than the CD release since the PCM-to-DSD conversion process will add some distortion to the original signal.
It's not difficult to detect these releases because of the "brickwall" loss of frequencies beyond 22kHz. Note that this list is of course unofficial and even though there's evidence that these come from 44 or 48kHz PCM, it's still possible they're from 24-bit data which could still be "hi-res".
An example of the 22kHz brickwall - Thelonious Monk's "Between The Devil And The Deep Blue Sea" off Straight, No Chaser SACD. Notice the typical ultrasonic 'noise shaped' SACD quantization noise from 22kHz up - filtered off in this case before 40kHz.
By no means do I believe this is a complete list - just ones I've run into over the years or confirmed by friends. I have tried to comment on these SACDs as part of my reviews on places like SA-CD.net but notice that these comments tend to get censored over time - I guess I can't blame them since they have something to sell :-).
Similar situations exist in the DVD-A world especially with upsampled 24/192 material (alas I never kept track of these but remember Frank Sinatra At The Sands was likely upsampled).

Zucchero "Sugar" Fornaciari - Rispetto (2004 SACD - DR6 dynamic compression, no better than 16/44. 5.1 track looks like DSP-derived "virtual surround". Just awful release.)
Interesting how the list includes "audiophile" labels and even demo/promo material like the Ken Ishiwata Marantz SACD, MFSL, Linn, even Japanese SHM-SACD. I think it also doesn't help the SACD cause that early Sony SACDs like the Brubeck and Monk are among these. I estimate about a quarter of the SACDs I've had a chance to evaluate consisting of eclectic rock, classical, and jazz disks are of the suspected-44/48kHz-upsampled variety.
Remember that I'm not saying these SACDs are bad sounding, just that in principle, the CD layer could be a more accurate representation of the music since there's no PCM-DSD conversion going on. In fact, many of these sound great and suggests that CD quality may be good enough. Unless there's a multichannel mix that you want on these disks or the mastering is somehow different (eg. less dynamic compression), IMO, there's no point paying extra for these SACDs.
Feel free to drop me a note if you know more about the releases (eg. can confirm if 24-bit source) or if you know of other upsampled disks.
Musical selection tonight: On an 80's kick right now. Going to have a re-listen to Midnight Oil's Diesel And Dust to get into the weekend mood... First pressing from 1987 of course. :-)
