Saw's ramp direction

[Michael G. Cox]

Curious,

The waveforms of LFSaw and SyncSaw both ramp from bottom to top.
Is there a reason that the Saw's ramp is reversed?

Also, why is does Saw's range go from -0.5 to 0.5 when almost
every other oscillator go from -1 to 1?
I assume it has something to do with it being band limited
since Pulse seems to have a similar range?
