I observe same results when setting XTERM to xterm-mono.
The terminal was actually xterm.
You can change vt220 to xterm-mono and see the same results.

I can do :echo line('.') col('.'). This shows me that cursor is not
where vim shows the white block on the screen.

I normally work in color xterm. There is no problem there.
I do not normally work in B/W term. What we were doing, we were checking how
some console software (not vim) behaves under the black-and-white TERM.
As a side effect, I noticed that matchparen behaves weirdly on B/W term. In
the mentioned B/W setup, the colorscheme was default because .vimrc is
empty.
Anyway, if you want to see the matchparen problem on BW term (with default
colorscheme), you can set TERM to xterm-mono and see for yousrself.
