S/4 HANA installation sequence HA scenario

ha-installation-sequence.jpg

Hello, im trying to understand the scenario discribed into the installation Guide - Installation of SAP ABAP Systems on UNIX : SAP HANA 2.0 Database - Using Software Provisioning Manager 2.0 in chapter 7.5 ( HA scenario ). => i want to install S/4 HANA 2020 in high availability.

You can find the sequence installation into the Attached file (coming from the installation guide chapter 7.5).

The questions :

1/In point B-2 why we have to install again the ERS / we already do this step on point A-4 ?

2/ In point B-3 why we need to install the content of host A HANA database remotely from host B ?

3/ In case there is a good reason for question2 so now why we dont do the same on the oposite side ( Install the content host B HANA database remotely from host A) ? how the database ( host B) will be installed ? by replication ?

Thx for your Help
