Symptoms can be: similar but the pathology or cause is different. True SI joint pain does not actually compress the sciatic nerve but can irritate it. It causes pain at the lower back and back of thigh. Piriformis syndrome can irritate and compress the sciatic nerve and the pain and paresthesias (numbness and tingling) it causes runs the course of the sciatic nerve, buttocks to the thigh and down the leg.

Yes/No: Rare that the SI joint can cause true sciatica, however it can cause a referred pattern of pain that is known to radiate down the back of the leg up to about the calf. Traditionally SI Joint pain most often causes tenderness and pain in the buttock area. Piriformis muscle may cause sciatica, but that is also not common. Suggest seeing a spine specialist to determine which is occurring.

Yes: certainly with time piriformis syndrome causes pain which may lead to an asymmetric gait - which will over time result in SI disease.
