Why did The Doctor wrote messages in English alphabet on the last day of The Last Great Time War?

The War Doctor wrote two messages on wall using blaster: "No More" and "Gallifrey Stands"

The alphabets were English. While TARDIS can translate, there was no one on Gallifrey who needed English to understand. So, I presume that that wasn't a translation of TARDIS, but that was really English alphabet.

What was the point of using English alphabets despite Daleks or Time Lords could decipher it?
