from my experience no.

my /etc/apt/apt.conf:

DPkg
{
// Auto remount readonly /usr
Pre-Invoke {"mount -o remount,rw /usr";};
Post-Invoke {"mount -o remount,ro /usr";};
}

works for me (TM)

note that as someone pointed out to me, if a package overwrites a 
file that is in use you will not be able to remount /usr readonly 
again until the file is closed.  so remounting read write always 
works but remounting read only again after the install/update may 
fail.

I use latest potato YMMV.
