connecting two macs via Firewire 800 - starting one from the other (as target disk) - which is then regarded as a non-SMART drive.

in Disk utility it is verified (looking at the external Mac/startup disk)

Disk Description : AAPL FireWire Target Media Total Capacity : 525,11 GB (525.112.713.216 Bytes) Connection Bus : FireWire Write Status : Read/Write Connection Type : External S.M.A.R.T. Status : Not Supported Connection ID : -6579310454868506820 Partition Map Scheme : GUID Partition Table

I just do not get it. Booting from the Target Mac that SSD is regarded as a smart drive.

Not all drive enclosures support SMART data. Your Mac in Target is one such enclosure. The hardware/software/firmware data paths to the internal drive from the FireWire connector or macOS are simply not identical.
