Pitting a lap after Verstappen would've put them behind on track and no realistic possibility of regaining the lead.

Ah, sorry. That was simply not wanting to concede track position and risk having to overtake on track despite having better tyres.
It's easy to appreciate why they were cautious in that respect.
