How many M.2 slots on the 15" Advanced OLED model?

The QHD model specifies an open M.2 slot for easy expansion, while the OLED model does not. However, they both say they're expandable up to 4TB. The specs on Best Buy clearly indicate that both of them have two M.2 slots, but I wanted to get confirmation before ordering. Thanks in advance!
