Hmmm... Well you've still got two separate audio paths (a 5.1 digital decoded and an analog one derived from that digital signal by the set-top) - there may be some difference, it's probably going to be close enough to not be audible. Much less likely than the delays induced by a TV. And thinking about it, it's actually a race - the analog signal coming from the set-top will be decoded by the set-top, while the digital signal will race ahead, to be decoded by the AVR. So the actual time delta would really be small.
I think you'll be fine, but if you want some insurance, make sure you can also run analog audio from the set-top to the AVR as well (if they're in the same stack, this would be trivial). So if there is an audible difference, you could switch inputs on the AVR to the "fallback analog 2-channel" source input when you're using the kitchen speakers at the same time.
