In arithmetic terms:

pitch1 = key + transpose + lever2 ∗ bend_lever_range
+ sweep ∗ (osc1_vibrato ∗ delay_envelope + lever1 ∗ mod_lever_range)

pitch2 = key + transpose + lever2 ∗ bend_lever_range
+ sweep ∗ (osc2_vibrato ∗ delay_envelope + lever1 ∗ mod_lever_range)

So you can see that it applies vibrato to both oscillators equally, and has
nothing to do with the filter.

There's also a less modern synth that lets you do this: the Chroma.
