There's a few variables to establish: which terminal emulator, which $TERM
(and corresponding terminal description) and which library mutt is linked
with.
xterm & ncurses I know firsthand - I recall that rxvt behaves similarly to
xterm, and that slang tends to use erase-to-end-of-line more frequently
than ncurses.
With xterm, erases will clear the flag that says a cell is initialized.
Uninitialized cells aren't selected. Blanks (and tabs) are selected.
Terminals that are setup to optimize for back color erase will use erases
more frequently since they can assume the colors don't have to be reset
after an erase - making that a cheaper optimization.
