Then there must be a recent change.

2018 NSA FP Rules

When a fielder obstructs a baserunner from making a base, (including a
run-down) unless the fielder is trying to field a batted ball or has the ball
ready for a tag.
EFFECT: When obstruction occurs, the umpire shall call
“OBSTRUCTION” and give a delayed dead ball signal for obstruction.
NOTE: Failure of the umpire to call Obstruction DOES NOT negate
the Obstruction.
1) If the obstructed runner is put out prior to reaching the base
they would have reached had there not been obstruction, a dead
ball is called and the obstructed runner and each runner affected
by the obstruction shall be awarded the base(s) in the umpire’s
judgment, the runner(s) would have reached had there not been
obstruction. An obstructed runner cannot be called out between
the bases where they were obstructed
EXCEPTIONS:
a) When an obstructed runner safely obtains or returns to the
base that he/she would have been awarded in the umpires
judgment had there been no obstruction, and there is a
subsequent play on another runner, the obstructed runner
no longer has protection by the umpire between the bases in
which the obstruction occurred and may be put out.
b) When properly appealed for missing or leaving a base

2018 NSA SP Rules have nearly identical wording. Both seem to be the same as USA
