Not if you bleed by gravity only.
I have found the fluid inlet often sits lower, close to the bottom of the "well", than the bleeder screw.
Change the fluid is best done by the "two person" method or pressurize the master cylinder or using the vacuum method at the bleeder valve.
The bad fluid needs to be pushed or sucked out of the system.
FWIW
