I just tried a RPi4B (USB3 SSD media) based on:

FreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20220923-00d8a28f19b-258155.img.xz

and do not see the specific behavior, if I interpret
correctly.

The system has (unchanged by me):

# more /boot/loader.conf
# Configure USB OTG; see usb_template(4).
hw.usb.template=3
umodem_load="YES"
# Multiple console (serial+efi gop) enabled.
boot_multicons="YES"
boot_serial="YES"
# Disable the beastie menu and color
beastie_disable="YES"
loader_color="NO"

I do use a different RPi* config.txt :

# more /boot/msdos/config.txt
[all]
arm_64bit=1
dtparam=audio=on,i2c_arm=on,spi=on
dtoverlay=mmc
dtoverlay=disable-bt
device_tree_address=0x4000
kernel=u-boot.bin
#
# Local additions:

uart_2ndstage=1
dtdebug=1
disable_commandline_tags=1
disable_overscan=1
#gpu_mem_1024=32
#
#program_usb_boot_mode=1
#program_usb_boot_timeout=1

# Old RPi3's/RPi2Bv1.2's may ignore [pi4] and the like.
# That would make the below inappropriate for such contexts.
[pi4]
# Locally avoid hdmi_safe's dislay scaling:
#hdmi_safe=1

# Local additions:

arm_freq=2000
sdram_freq_min=3200

#

The video console had much of the material but,
for example, had:

. . .
random: unblocking device.
GEOM_PART: da0s2 was automatically resized.
  Use `gpart commit da0s2` to save changes or `gpart undo da0s2` to revert them.
lo0: link state changed to UP
genet0: link state changed to DOWN
ue0: link state changed to DOWN
Starting Network: lo0 genet0 ue0.

and so the video console was missing the likes of:
