Yes: the transition from H(1) to H(0) means from RM to UDH.
I'm not sure if this could be regarded as an acceptable answer in this context, but I'll report anyway: a few days ago I sent Leif Holmlid an email asking a couple questions regarding the practical usage of the condensation energy of H(0). Incidentally, part of his reply might be relevant here. Summarizing, he wrote that while in principle it's possible, such energy tends to get retained in the material in the form of inner motion (rotation) of the H-H pairs in the superfluid H(0) clusters along their main axis (schematic diagram here) with no loss of energy to the surrounding, similarly to what happens with regular molecules in superfluid helium (random example from a Google search where this effect is cited). This is also what the oscillation between the H(0) and H(1) forms as reported in earlier works implies, from what he writes.
So, my guess is that this energy would not necessarily have to be provided all at once. After all, so far he's used a Nd:YAG laser typically at 532 nm (2.33 eV per photon) or 1064 nm (1.77 eV per photon) to break up the ultra-dense material in his experiments.
