No longer need to avoid Halls of Pain WP to keep Pindleskin?

So I was running one of my necros thru NM to get thru nilathak quest, and in HoP to my horror! I accidentally rolled over the WP there. After cursing to myself, I finish up NM, and then out of curiosity, I relog and create a new NM game after killing

Baal and unlocked Hell difficulty.

To my surprise (and relief)! I find that the Nilathak's Temple red portal is still active, even though I activated the

Halls of Pain WP. Was still able to farm Pindle after touching that WP that was not to be touched in the original D2LOD.

Is this feature something that was improved in D2R as part of 'quality of life' changes? I suppose I'll be safe to activate the WPs in Hell too so I can keep the easy

Pindleskin access? Pardon my ignorance, lol.
