Small Clone power supply

I'm experimenting with the EHX Small clone, but don't really understand why they put the transistor at the start of the circuit, why not just have a bit of filtering instead of the extra stuff.

Just curious.

I should add, I'm using two LM13700 OTA Ics instead of multiple CA3094s.
