Are those two 10% figures equal only by coincidence?

To me, "boost membership by 10% above trend" means either "increase this year's signups by 10% of what they would otherwise have been" or else "increase this year's signups enough to make membership a year from now 10% higher than it otherwise would have been".

The second of these is equivalent to "membership will be 10% higher a year from now" iff membership would otherwise have been exactly unaltered over the year, which would mean that signups are a negligibly small fraction of current membership.

The first is equivalent to "membership will be 10% higher a year from now" iff m+1.1s = 1.1m where m,s are current membership and baseline signups for the next year, which is true iff m = 11s.

Those are both rather specific conditions, and the first seems pretty unlikely. Did you actually mean either of them, or have I misunderstood?

I am reading the grandparent literally as "increase membership" which does imply that the current trend is flat and the membership numbers are not increasing.

Could be. But is Alcor really doing so badly? (Or: does James_Miller think they are?)

The graphs on this Alcor page seem to indicate that membership is in fact increasing by at least a few percent year on year, even if people are no longer counted as members after cryosuspension.

Hm. Yes, Alcor's membership is going up nicely. I don't know what James_Miller had in mind, then.
