Uzuhiko has two distinct components: the physical damage and the psychological damage. For the psychological damage, we see this demonstrated when Code is hit by the initial Rasengan. The attack then embeds itself inside him. Boruto states that the energy (a combination of his chakra and the absorbed planetary chakra) rushing ‘inside’ the target is tied to the planet’s movement. Since the planet’s movement never stops, the attack itself is perpetual and unending.
For the physical damage, in the case of Hidari, boruto can actively absorb more chakra from the planet to amplify the attack, as he mentions. Importantly, Boruto doesn’t just appear to tether the energy at least based on his explanation. He took in the chakra first before using it. For this, the goal was not to embed the chakra into the target in the case of code but to destroy the target completely. We saw that even a part of Hidari was trying to escape before he was destroyed by Kawaki in that moment the psychological effects were of no use because Boruto's goal was to destroy Hidari on the spot.
Boruto said “I quote I need to take in the planetary chakra through both feet on the ground, and to kill him with one blow I will need quite a lot of it” So as you can see he absorbs the chakra not tether it.
Prior to this Sarada had asked Boruto to fly up and use his Normal Rasengan, but Boruto says no instead he will use Uzuhiko at the maximum Output. Then Sarada asked again can a single shot of this just take him down.
Then Boruto said it is possible if I don't hold back. Proven that he can absorb little or less of this energy.
Here we saw that Boruto was not done with the absorption he says it was not still perfect, meaning he could still absorb more chakra to reach a maximum output.
people confuse feasibility with possibility. But uh, just wait, I’ll be proven right before the arc ends
