fix: improve readability of comment,

[billybonks]

I was reading through the spec and this sentence seemed a bit off due to the in and symbol alliteration.

I didn't find any contribution guides so not sure:

1. if my commit is formatted properly
2. if i should have changed the historical specs

Thanks in advance
