Yep. Honestly the popdog as the train makes way more sense to me. Back in 1.6, there were 2 popdog trains - one at inner (train by the ramp) and one at outer (train right by ladder room). Obviously only one of those trains still exist in CSGO.
I think if people refer to pop as the area right outside ladder (by double stack boxes) or in between ladder or e-box it's fine, but I'll never understand why the ladder room itself became popdog.
