That is an actionable improvement idea to introduce a synonym ;-) But in general, the way the internal "git grep" machinery is exposed to the commands in the "git log" family is very limited. With "git grep", it is quite straight-forward to say "report hits for lines that has this but not that" $ git grep -e this --and --not -e that but because that the commands in the "log" family already use "--not" for a quite different purpose, "git log --grep" cannot even express something similar, even to find hits on a single line, let alone finding hits on two different lines (i.e. one on the "author" header, the other in the message part, of the commit object).
