The OpenSSL command line contains lots of options to convert between ... Multiple -and -or in PowerShell Where-Object statement. By wrapping your comparisons in {} in your first example you are creating ScriptBlocks; so the PowerShell interpreter views it as Where-Object { <ScriptBlock> -and <ScriptBlock> }.
