A fast and stupid question about upgrade

Installing and Using OpenWrt
1

I see openwrt use on my router two images

avm_fritz7490-micron-initramfs-kernel.bin

and

avm_fritz7490-micron-squashfs-sysupgrade.bin

for installation I flash first the image initramfs

and then

sysupgrade -n with avm_fritz7490-micron-squashfs-sysupgrade.bin

I see for sysupgrade they use only the avm_fritz7490-micron-squashfs-sysupgrade.bin image, it update also the initramfs?

Initramfs is for install only (if needed).

initramfs is meant to netboot oem or otherwise inaccessible device without altering flash memory. Once you run openwrt you only need sysupgrade images.
