Illegal player...libero

[john5396]

Note, I dont work USAV, so I'm not familiar with the rule particulars, but in the Interp referenced it has:

NOTE: Attention must be paid to the difference between a player whose name is not listed on the roster
and a player who is listed on the roster but with the wrong number. This case specifically deals with a
player whose name is not listed on the roster, and is the only time the referees may go back to previous
sets to remove points. In addition, tournament eligibility rules, such as region guidelines or the USAV
Qualifier Manual, may supersede the roster (eligibility) rules.

So with this qualifier, was it correct to cancel the points in Set 1?
