If I understand well, you mean select mode LSB, shift the filter to the
right to the position where the USB filter roughly should be and
listening for example in 20 m, he hears the USB signals clearly? Well,
of course, this is true, it can be verified by anyone regardless the
operating system. It is the equivalent in an analog receiver to install
a USB filter in the LSB path, the demodulator is the same. There were
receivers (expensive) with independent filters for each sideband which
allowed for ISB mode.
If you didn't verified that probably is because the filter was not
shifted to the right position or the station you heard was using the
inverted sideband. Or I misunderstood the whole thing, which is normal.

A fellow flexer using an SDR1000 and Windows 7 told me that if he slides his
filter from LSB to USB he is able to hear USB signals on USB clearly. I tried
it with mine, using WinXP and did not experience this. Has anyone else see seen
this?
