Yes, that's why I initially assumed it was a triplet. But I'm pretty sure their previous SV50 apo (doublet) was also listed in that section. Plus, all the other scopes in that section actually have "triplet" or "quad" in the name, so I think the SV60 is probably a doublet.

The site says it has FPL-53 glass in the lens, which would be sufficient for a colour-free doublet at 60mm aperture.
