I think so. I seem to remember the installer does the adequate incantations so
that the path settings have immediate effect (Tomek can surely confirm or infirm

No. This point always surprises me, but the system path takes precedence.

It has a practical consequence : if you installed TL2009 system-wide, and
install TL2010 only for your user, then TL2009 will continue to be used, and
afaik there's nothing we can do about it. Hopefully this case will be rare.
