Actually, I did find it:

http://vt100.net/docs/vt520-rm/ek-vt520-rm.pdf

It states:

2.9.7 Erase Color
The Erase color selection controls the background color used when text 
is erased or new text is scrolled on to the screen. Screen background 
causes newly erased areas or scrolled text to be written using color 
index zero, the screen background. This is VT and DECterm compatible. 
Text background causes erased areas or scrolled text to be written using 
the current text background color. This is PC console compatible and is 
the factory default.

Note the second clause of the last sentence.

This still holds, of course.
