Default Callbacks in share/html/Ticket/ModifyAll.html and share/html/Ticket/Modify.html

In share/html/Ticket/Modify.html there is such description of Default
callback:

$m->callback( TicketObj => $TicketObj, CustomFields => $CustomFields,
ARGSRef => \%ARGS, skip_update => \$skip_update, results => \@results );

As result it is possible to add user messages to @results list

But in share/html/Ticket/ModifyAll.html there is such description of Default
Callback

$m->callback( TicketObj => $Ticket, ARGSRef => \%ARGS, skip_update =>
\$skip_update ); 

As result is it impossible to add users messages to result list.

Is it issue or I can not understand something?
