That's correct.
See https://git.kernel.org/pub/scm/linux/kernel/git/deller/palo.git/tree/ipl/ipl.c
line 570 and following.

palo checks your system.
In case you haven't given a "console" line, it and will add
something like "console=ttyS0" when you are accessing firmware/IPL
via serial port.
If you have a keyboard connected with a monitor, it will add "console=tty0"
and add the "sti=<hardware-path>" options.

I'm not 100% sure, but I think Linux will only print the initial boot
messages to either serial port or to the screen. That's what the
console= option is about.  
I don't think this limitation is parisc specific.

After bootup, Linux can of course show a login prompt on both serial port
and screen if you adjust /etc/inittab.

Good, Ok.
