We use lower-case h when we know which laryngeal it is, and upper-case H when we don't (h₁, h₂ and h₃, vs. H). It's inconsistent to mix an upper-case form like Hʷ with lower-case forms like hₓ: the paper you linked to seems to consistently use upper case for everything, so case doesn't mean anything in that context, and doesn't have to be followed. As for the *Hʷ notation itself, the problem is that it makes it look like it could be any laryngeal, but with rounding added, rather than a specific unknown sound that has the property of sometimes causing adjacent vowels to become rounded. I would convert your to notation to ours like this: Thus, *Hʷet- would be our h₃et-
 * hₓ = H
 * Hʷ = h₃
