In a straight ahead descent, the wing is producing 1g lift and the stall speed is the same as in level flight.   You guys may be thinking of the change in stall speed when *initiating* a descent (pushover, less than 1g for a moment), or when *terminating* a descent (pull-up, or flare, momentarily more than 1g).

In a descent, the stall speed is different because the wing is not lifting the same weight as it would be in level 1-G flight.  However, that only accounts for the vertical component.  The hi-G turn (like 70 degrees of bank) is still adding sgnificant load to the wings.

more reason to practice at altitude and see if this is something you might want to include in your bag of tricks
