Multiplus 3000 and second DC output

I would like to know why, on this diagram (https://www.victronenergy.fr/upload/documents/MultiPlus-3KW-120VAC-12VDC-400Ah-Li-VEBus-BMS-generator-MPPT-BMV-Cerbo-Orion- Tr-Smarts.pdf), the dc outputs 2 are connected to the lithium battery bus and the starter battery is connected to a small charger. According to the specifications of the multiplus 3000, the dc output 2 is intended for a starter battery and only produces a current of 4a. So, why not use output 2 for the startup bank?

The second output follows the charge profile of the internal charge profile.

Lead and Lithium have different needs.

And it is just an example demonstrating product configuration and uses possibilities not necessarily the only way it can be done.

I understand that it is therefore not possible to program 2 different charge profiles. As my configuration is similar (lead and lithium), is there an advantage to connect the second output to lithium bank other than providing an additional 4a?
