Actually Read the Rules
The chaulk line goes to the back angles of the plate and not the front of the plate.
Edited to add:
Her foot is on the base line in the first collision as well. She is in the basepath. The basepath is not only in the foul area beyond the line. It includes the line and the front of the plate.
Something must be lost in translation here: the base path has nothing to do with the foul line. USSSA and ASA hands books on hand neither even remotely mentions the line. Only the well known "imaginary" direct line between the runner and their next base. I don't have my NFHS rule book with me but I'm fairly certain there is no mention of the line in that rule set either.
USSSA Definitions: BASE PATH. A base path is a direct line between a base and the runner’s position at the time a defensive player is attempting (or about to attempt) to tag a runner.
