No, he very clearly does not state that he washes or reuses them. Here is the clothing section, in full:

--- I enjoy doing laundry about as much as doing dishes. I get my clothing custom made in China for prices you would not believe and have new ones regularly shipped to me. Shipping is a problem. I wish container ships had nuclear engines but it’s still much more efficient and convenient than retail. Thanks to synthetic fabrics it takes less water to make my clothes than it would to wash them, and I donate my used garments.

It bothers me immensely that all clothing is hand made. Automation is woefully absent from the textile industry, but I don’t think it always will be. For now a few new t shirts and jeans per month is not very offensive. I certainly buy less clothing overall than a typical consumer. Synthetic fabrics are easy to recycle and I believe will soon be made with biofuels. Still, this area needs some work. ---

The only reference to washing them is the water savings of buying new over what it would take to wash them; now, he also says that he buys "a few new jeans and t-shirts each month" and "less clothing than the typical consumer". Now, those descriptions appear to conflict, and either one of them seems to suggest enough reuse that many people would assume he must be washing them a few times -- going with the first (which is the one least indicative of reusing clothes a lot), and assuming "a few" is not more than 5 of each, he'd have to be wearing each at least ~6 times, which seems a lot without washing. But he doesn't say he is washing, that's just an implication that is easy, though not necessarily correct, to read into his statement.

That is correct that he says he doesn't use a washer or dryer, however it is incorrect to saw that he washes and reuses them with the information provided. He says it takes less water to make the clothes than to wash them, not that he actually washes them. In fact, he says he donates his used clothing, not mentioning if they have been washed or not.
