CRT TV as monitor working backwards

[KP <kjpmail@gmail.com>]

I plugged a IIgs composite-out into the composite-in on a 13" CRT
Sharp TV.  Much to my surprise, I was shocked that, when put in
GRAPHICS mode (lo-res, hi-res, any res), the picture is crystal clear
(including the text portion of the screen in GR or HGR mode).
Likewise much to my surprise, I was further shocked that, when put in
TEXT mode, the text is ludicrously fuzzy and blurred.  The latter
effect disappears when I reduce the COLOR setting on the TV to 0.

See, I thought that the composite out was supposed to be super clear
in text mode, and that it was the graphics modes that were supposed to
struggle.

This is a Rom 01, if that matters.  I just don't know what's going
on.  I was expecting portions of the experience to be uncooperative,
but I had expected the opposite problem from what actually happened.

Is this normal?
