Everything related to toe is out of specs. Their numbers for minimum and maximum are wrong, and where they set them for the rear will lead to inside edge wear for sure.
For the front tires - assuming they're 225/40/18 - each millimeter of toe is roughly 0.1798 degrees. Spec is 1mm +/- 2mm. So total front toe should be -0.1798 to +0.5395 degrees, not -0.15 to 0.40 degrees as listed on the sheet. The minus number is toe out. Somebody didn't use the right tire size when calculating those angles.
For the rear tires - assuming they're 255/40/18 - each millimeter of toe is roughly 0.1733 degrees. Minimum spec is 1mm, maximum is 5mm, both are toe in. So Lexus spec is 3mm +/- 2mm or 0.5199 degrees +/- 0.3466 degrees (0.1733 to 0.8665 degrees is the acceptable range). Your setting, IME, should be at minimum spec for longest tire life, so your total toe should be 0.1733 degrees.
At 0.9 degrees total toe in the rear (where they set yours), you're at 5.1935mm which is WAY too toed in and IME will kill the inside edges of your tires very quickly. This is the setting you'd use for a track car where turn in is the primary concern and tire wear is a secondary consideration, not a street car where tire life is the greatest concern.

I'd go back with their own spec sheet and point out where it says maximum spec in the rear is 0.70 degrees and they set it to 0.90 degrees. Then I'd insist on a fresh alignment because they didn't even set it to their own specs.

He's either an idiot or a liar. There is no camber adjustment on the IS350. The only 2IS with adjustable camber is the AWD. Besides, incorrect toe will kill tires far more quickly than excessive camber. This guy sounds like a typical alignment monkey who doesn't understand anything except the green indication from the computer. I'd take it back, ask to see the manager, show him the sheet and tell him you want the toe corrected to OEM specification. Also, from TIS:
PM me if you need more documentation.

The toe-in will change by the following amount corresponding to each graduation of the cam: Approx. 4.0 mm (0.16 in.)
