Does that not work? I would expect it to.

For settings which are available as variables the common practice is to 
stash the "current" value in a $my_something variable, change it, then 
set it back. Crude and only single level, but usually enough. Example 
from my muttrc where I turn off $wait_key to stop mutt pausing during an 
operation:

These 2 lines define a command string to save the current $wait_key then 
the beginning of the "set wait_key" command, then another string to 
reverse it:

    set my_push_wait_key=':set my_prior_wait_key=$wait_key; set wait_key'
    set my_pop_wait_key=':set wait_key=$my_prior_wait_key<enter>'

Then they get used in my rot13 toggle command string:

    set my_toggle_rot13="$my_push_wait_key=no<enter><shell-escape>flag !  MUTT_ROT13 -e flag MUTT_ROT13<enter>$my_pop_wait_key"

and then I've got some mac ros to run the toggle:

    macro index \Cx "$my_toggle_rot13" 'toggle MUTT_ROT13'
    macro pager \Cx "<exit>$my_toggle_rot13<display-message>" 'toggle MUTT_ROT13'

The mechanics don't really matter, just the shuffle of the original into 
and out of $my_prior_wait_key. You should be able to do the same with 
$implicit_autoview.
