Just because a statement's meaning is clear doesn't make it easy to read. Even seemingly minor errors (such as mixing up "it's" with "its") disrupts the flow of reading.
Also, all this discussion about grammar is useless noise which should've been taken privately in order not to interrupt the flow of ideas that might improve the software.
So, please, in the future redirect grammar nitpicking efforts to a more appropriate place like StackExchange's English Language and Usage [1].
