`ctx = pushop.repo[node]` is needed to check the phase of the ctx. also, iiuc, if i write `if a and b: pass` in python, both a and b are evaluated before performing the comparison. iiuc, when ctx is `None`, `ctx.phase()` won't exist as `ctx = repo[None]` is not actually a changeset but, the uncommitted changes in the working directory instead. if we need to skip the return, we need to have the `ctx = pushop.repo[node]` inside the `if` statement. but, for me, skipping the further evaluation earlier using a `return` without the nested `if` with more alignment sounds good.
