Przemek,
Your understanding is correct. If you have an iBGP and an eBGP learned
prefix, BGP selection criteria will decide which route will go to the
routing table (In most cases this will be decided earlier than the "ebgp
vs ibgp" comparison)

eBGP over iBGP. It's step 7 in the link your reference below.
Thanks,
