Into the shadows and vaders end of round action

By topacesteve, in Imperial Assault Rules Questions

Hello, if i play Into the Shadows on a smuggler can vader force choke him at the end of round if his is 5 spaces away?

Yes.

Q: When an ability's effect lasts "until" a certain timing
window (e.g. "Until the end of the round..."), does that effect
persist through that timing window?

A: No. These abilities' effects end immediately as the specified
timing window begins, before any other effects in that timing
window are triggered. So, in the given example, the effect that
persists "until the end of the round" would expire before any other
"end of round" effects are triggered.
