Does A380 top deck Y board with J ?

[Andona]

We have our first flight on an SQ A380 coming up and have seats allocated in the top deck Economy cabin. When we've flown on Qantas A380 in similar seats we were advised that top deck Y were welcome to board when business class was called, and did so.
I was wondering if a similar system applies with SQ? Or should we wait til Y is called for boarding?
Ive tried searching the boards to find the answer with no luck, so apologies if this is a dumb question.
TIA

I departed from Singapore on an SQ A380 last night. Upper deck economy passengers were called forward for boarding with "boarding group 4", which was the first group of economy passengers (all upper deck Y and rear lower deck Y pax). This was after First, business class and premium economy had been called. Of course, upper deck passengers were directed to board via the upper deck airbridge (shared with business class) after having boarding passes scanned.

Thanks MattG, that's exactly the information I needed.
