Because .bashrc is not loaded by login shells. Read the manpage of
bash(1) for more details, and make sure you pay A LOT of attention
to the ``INVOCATION'' section:
When bash is invoked as an interactive login shell, or as a
non-interactive shell with the --login option, it first reads
and executes commands from the file /etc/profile, if that
file exists. After reading that file, it looks for
~/.bash_profile, ~/.bash_login, and ~/.profile, in that
order, and reads and executes commands from the first one
that exists and is readable. The --noprofile option may be
used when the shell is started to inhibit this behavior.
When a login shell exits, bash reads and executes commands
from the file ~/.bash_logout, if it exists.
When an interactive shell that is not a login shell is
started, bash reads and executes commands from ~/.bashrc, if
that file exists. This may be inhibited by using the --norc
option. The --rcfile file option will force bash to read and
execute commands from file instead of ~/.bashrc.

Yes. This is no longer a login shell. It's merely an interactive
shell, so bash ignores .bash_profile and reads .bashrc instead.

My preferred setup uses both files.
The .bash_profile file acts solely as a 'delegation script', which loads
all my preferences from .bashrc. The full contents of my .bashrcc file
are something like this:
test -f ~/.bashrc && . ~/.bashrc
true
All my preferences, options, environment variables, and other bash
configuration is stored in ~/.bashrc.
This way both login shells and interactive shells use precisely the same
environment.
