I (still) think that depends on NPOT texture support in the device.
I.e., if the device doesn't support NPOT textures, I suppose the call
can either fail, or create a texture with different dimension like
64x64, but it can't create 63x63 textures. Note that
D3DPTEXTURECAPS_NONPOW2CONDITIONAL also affects NPOT capabilities.
