This makes sense, because perhaps the world's most important email client that still costs money to buy (Outlook) used the terms SSL and TLS like that for about a decade. These days the toggle says "SSL/TLS" versus "STARTTLS", I believe, or they may have even dropped the toggle completely to just auto-detect the protocol based on the port number. Using correct terminology would've led to tons of unnecessary helpdesk calls because Microsoft messed up its naming scheme.
