He would have to have gone back to taxi within 30 days of waivers (I think)
Which he may have.
i am not a CBA expert
but per below, it seems was waived Jan 11, first called up on Feb 1
and most recently assigned to taxi on Mar 5 -
perhaps while he was injured, the clock was stopped?
or might each assignment to taxi (or minors) re-set the 30-day clock?

UPDATE - found this at CF, seems the 30-days is cumulative, and so it seems time on Taxi halts the 30-day count:
Waivers FAQ - CapFriendly - NHL Salary Caps
A player does not need to pass through waivers if the player has not been on the NHL active roster for a
cumulative 30 days since last clearing waivers, and has not played in 10 or more NHL games. CBA Reference 13.2(b)
