With disk #3 about to die, I'd have felt safer if it first finished rebuilding the replacement disk for failed disk #1 (that rebuild had almost completed at that point), safeguarding the array against a third disk failure.
I agree, the current arrangement seems to throw away a significant amount of work. Yes, you will need to resync when re-adding the second disk, but in the meantime might as well try to get a redundant mode at all costs.

You could finish the last little bit of the resync of the replacement for failed disk #1 (by looking at P+Q), and then re-sync the replacement for failed disk #2 (by looking only at P..) -
