STM32G474 Timer X register update behaviour when CONT=0 with RETRIG=1

When TxRSTU and RETRIG are enabled with CONT disabled, will the timer still trigger a register update when it's counter reaches it's PER value? Since it says in the image below that the PER event is generated but says it re-starts from 0 when it's reset but doesn't mention roll-over, and the image above says it'll update registers on timer reset and rollover. Essentially what I'm asking is does it count as a roll-over when the timer reaches its period value when CONT=0? Since I need to know if it'll update it's registers at the end of it's period or no.
