Meow, my personal guess is just that -- a guess...but a one-time MA level treatment on a liner that's in decent condition (yours is new) isn't likely to impact the integrity of your liner, particularly when performed by someone paying attention to testing parameters, including cya, which buffers the chlorine.
There are folks who blindly dump powdered shock into imbalanced pools and old liners regularly without major damage.
My vinyl liner sat with crashed ph for two years as a foreclosure, and I got another five years out of it before the wear became aesthetically displeasing to me - for a total of 15 years
The SLAM values of TFP are actually much less aggressive (but consistent and comparatively precise, which is key) than the treatment approaches used by many pool techs in recovery scenarios.
Time and sun have as much to do with liner wear as chlorine. Super low ph (eg under 7) will reduce preservation of the vinyl components moreso, IMHO.
So no worries
