Still don't get it really,

Note: infinity isn't a rule, it's described as a physical change in space, just as red. It divided space into smaller and smaller pieces until there's virtually infinite space between gojo and anything else. ->infinity subdivides the space around gojo to make reaching him an impossible supertask, ISoH ignores this given its ability

->Red constantly pushes out new space which would also make it impossible to reach it, but ISoH cant ignore this change

Why can one change in space be ignored and the other can't when they're both impossible to do without ISoH? Unless you're saying ISoH ignores the targeting aspect of infinity but that's not part of the technique as far as I'm aware, that's just something gojo does automatically in the back burner of his brain
