Need help understanding a technical spec

I am looking at a STW8T36B LED and trying to understand what the spec us stating

Because this part has 3 independent Diodes it is not clear to we whether the Seoul Specs are per diode or per the package

Max Vf = 3.5
Max If = 90ma
Max Pf = 325mW

I would assume that this is for each diode?

When I went to school in the 70's LED voltages were 1.5 Vf at 10ma so is this how they are getting the higher intensities by doubling the voltage and upping the currents?
