Or, to be more precise, *h1sú- and *h1wésu-. It could, though there
are no unambiguous traces of the expected digamma. In a few words
Greek seems to have a reflex of laryngeal-less *su- (the
simplification probably took place already in PIE before a heavy
syllable). My personal suspicion is that PIE *h1sú- represents an
irregular compositional reduction (the "weak form") of *h1wé(:)su-, so
the two roots are ultimately the same.
