'Mono' Cartridges vs. Mono Buttons


Hello,

I recently got into vintage 'microgroove' mono vinyl and I'm interested in getting the most out of my new records. I can either use my Shure m97xe stereo cartridge and just push the mono button on my amp (as I do now), or I can purchase a new, entry-level mono cart.

In replies from Grado and Ortofon I have learned that the Grado MC/ME+ and the Ortofon 2M Mono are both vertically compliant, multi-coil "mono" cartridges configured to cancel the vertical signal from the groove internally, and that this is not done by bridging the left and right channels.

So does pushing the mono button on an amplifier when using a stereo cartridge also cancel the vertical signal? I have my suspicions that it bridges the channels, and though this improves the signal-to-noise ratio (boosting the "mid" output more than the "side" output in mid-side terminology) while 'masking' the 'stereo noise' by placing it in the center image along with the music, it does not cancel the vertical signal...?
