Exhaust valves are open during the exhaust stroke anyway. Inlet valves are open during the intake stroke anyway.

The strongest plausible interpretation of what¹ they're saying is to open valves that are partway through the compression stroke, and open / close any other valves as necessary at the best possible time to promote rapid starting.

that really makes the most sense. at that point i imagine it would be a more finely controlled compression release. i shouldn't read too much into the wording of what is essentially a marketing statement i suppose :)
