what if my recommender is not good at...

my supervisor (a required recommender) is old and not very good with online submission of recommendations. My supervisor is also not very good at english grammar (dispite been a noooo yawker for o entire life). What if my supervisor makes a few grammatical mistakes while filling out online recommendation? Would that impact me negatively?

p.s. My supervisor already submitted the recommendation online, so telling me to get paper copy and send it probably wouldnt solve the problem here.

Thanks for your help!
