Exactly. I have done this twice with luggage (3 times in total, the other time was HBO). The luggage will appear (eventually) at Belt 8 in reclaim.
However, now that the OP is ticketed on EI, I guess the bags will be whisked to T3 on arrival, so may need to collect them there if the passengers somehow get lost on the way to the EI gate
