I just popped on my newly remastered rear brake calipers from PMB and was wondering if there was a point to the lower bleeder? I only ever bothered with the top bleeder before but now that it's bone dry I was wondering if that might be why the second bleeder exists? I will be bleeding the brakes tomorrow morning.

Ferrari 308 uses the same rear calipers. I think the double bleed screw is to accommodate use on it.

No, the Ferrari caliper is completely different.
The Ferrari caliper is similar to the 914/6 rear caliper, physically larger since it uses the same brake pads as the 914 front calipers not the tiny 914/4 rear pads. The Ferrari caliper has the handbrake lever on the opposite side and hence the single bleeder is on the opposite side also. Further, the Ferrari caliper has two identical pins for the pads, not a large and small combination.
I was looking around for some 914/6 rear calipers some time ago and came across a Ferrari caliper for sale that was converted to Porsche style by adding a second bleeder. I had the shop convert a 914/6 rear caliper to have dual bleeders so that I could have a matching pair; well not really, the one has 2 small pins and the other has the large/small combo.
