The note is poorly worded, but I believe it tries to refer to https://www.openstreetmap.org/relation/7239851 . Among the 3 parts, I take "u turn" and "Tuen Mun Park" to construct a consistent info piece.

Then, regardless of whether a survey is planned or not, this https://www.openstreetmap.org/changeset/182239427 must always be correct.

I intend to unsubscribe from this.
