I asked my HSA administrators a question, and this "sentence" was the reply:
Thank you for your reaching out to us, with regards to your question if you're trying to pay your provider for an amount lower what is available on your HSA cash balance it will decline, unless you're going to pay them what is left in your HSA cash balance then pay the half via out of pocket then once you initiate your cash replenishment to your investments then you can file a reimbursement request later.

This one looks more like plain old speech transcription software. Look at the commas: they're at natural pause points if someone said this run-on sentence out loud. Oh, and the speaker probably took a small breath after the word "pocket". The software then added a sentence boundary there, which the speaker went back and manually removed, accidentally keeping the double space.
