tasty pot and bamboo table mats

I got this pot last year. It was from Walmart, and the perfect shape and size for cooking pasta and stews, etc. (My old pasta pot was enamel, decades old, and had gotten chipped inside, leading to enamel chips in the food. After that happened to a meal, I knew I needed a new pot.) It also happened to be the only pot I had to whose base a magnet would stick, and which could therefore be used on the induction burner I got this year. It also happens to be beautifully reflective.

Today I went to Walmart and got another pot of the exact same kind, to keep at Qiao's house along with the induction burner. This was the first time I've been to Walmart since last year.

Comparing the new pot's cardboard label to the old one (I take photos of such things for future reference), the old one said "Oven safe up to 400°F". The new one says "Oven safe up to 350°F". The accompanying booklet further restricts it to "Oven safe up to 350°F for up to 30 minutes". I wonder if the new pot is manufactured differently than the old one, or if they got too many warranty claims for pots damaged at 400 degrees, and simply updated the labelling. I don't use the pot in the oven, so it's only a matter of curiosity for me.
