Is that a mistake or..?

You said, "filling." I thought you meant you'll fill up your depot, lol. My bad.

"Refilling" from the depot makes more sense.

yeah,,, not going to let that slide.
He said 'filling from dp from now on..'
perfectly clear, with or without a 're' prefix.
Whether he is filling himself up from DP or returning to a filled up state from DP makes no difference. Implying is does is well...
