The previous spec was obviously fine reliability wise in Gasly's car so having one old and one new gives them the opportunity to compare them in proper conditions, not just the bench - especially since the STR is nothing but a test mule for RBR this year.
Whether this means they don't expect a huge jump in performance or not would be pure speculation.
Redbull will want to know the reliability as well. If Gasley's unit survives Canada it would reach the target of 7 race weekends.. they don't need a top driver to find how much power the new unit is making , with access to str data, they can just find it from the straights..
