No, the remove is always done with the client, but there is also the 
update run before the remove, if there is one pending, so you can fix 
the remove command and it will be fixed just before the remove.

When I find that a remove command needs an update, but not the 
application, I do the following:

1) correct the remove command(s)

2) increase the package revision
    a) if I use the application version as the package revision,
       i) I append the current date
          revision="%PKG_VERSION%" gets
          revision="%PKG_VERSION%.2016.07.16"
       ii) if I have to change it multiple times on one day,
           I append the time of day too
           revision="%PKG_VERSION%.2016.07.16" gets
           revision="%PKG_VERSION%.2016.07.16.23.23"

3) add the attribute >>precheck-upgrade="always"<< to the package
    to make sure the update code is only run when really needed

This way the remove command(s) get updated before the remove.
