Only because it is unmasked.  You could always mask 3.4 to keep it from
installing.  Yes, this is your choice.

You could also remove 3.3 after doing your bootstrap.  Remember that
part in the Handbook that says you really shouldn't be playing around
with bootstrap if you don't know what you're doing and willing to do
work on your own system?  Here's a prime example.

Again, this is completely because of you not making any changes on your
system.

Which you won't have to deal with for long, 2006.0 is being worked on as
we speak.  The basic jist of this is that what you are seeing is pretty
much expected behavior for bootstrapping using a stage with an older
GCC.
