Yes it is. Note in the drawing that the o-ring I specify, has a cross-section (thickness) of 0.157" and the OEM o-ring is 0.117". You are absolutely correct that the result is "greater compression" ( I prefer to call it proper compression) but the results would be increased differential pressure sealing capability. The stack height of the o-ring groove depth plus the compressed gasket thickness is only 0.004" less than the OEM o-ring cross section (thickness), putting only 0.004" compression on the o-ring, the same amount as an ordinary sheet of copy paper is thick.
