As worded here IMO it would be better described as being partially blocked and by definition has crossed the NZ once it touches the ground or anything else in the field of play that is beyond the NZ.
Rule 2-16-7-b. A scrimmage kick has crossed the neutral zone when it touches the ground, a player, an official or anything beyond the neutral zone (Exception: Rule 6-3-1-b) (A.R. 6-3-1-I-IV).
The key wording is included in AR 6-3-1-II
II. Team A’s untouched punt or field goal attempt goes beyond the neutral zone in flight, is blown back by the wind and first touches the ground, a player or an official behind the neutral zone.
RULING: By rule, the kick is not considered to have crossed the neutral zone until it has touched the ground, a player, an official or anything beyond that zone. Any scrimmage kick may be advanced after catch or recovery by Team B, or after catch or recovery by Team A in or behind the neutral zone if the kick had not crossed the neutral zone (Rule 2-16-7).
