Yes, exactly this is the case. WPKG has a feature I call 
"upgrade-before-remove". It was introduced to help package admins to fix broken 
packages easily. So if you made a mistake, let's say your flash10 package 
installed to clients does not correctly uninstall (maybe you just forgot to 
specify correct remove commands) then you don't have to worry. Just fix up your 
flash10 package on server side, bump the revision number and remove it from the 
profile.

WPKG will then first upgrade flash10 to the latest available revision to assure 
that the latest/fixed package is applied to the system. Then WPKG performs the 
remove.

WPKG will still first perform all removes before performing any installation. 
But as you see in some exceptional cases (client runs outdated version of a 
package to be removed) an upgrade will take place right before the remove.

Hope this makes any sense to you ;)
