    _______________________________________________________

Details:

title may be a bit cryptic, but basically if given a series of commands, and
an intermediate command results in calling the pager, the next command
executes but is not echoed to the terminal.

Example:

no pager call

>> rand(3),7+7
ans =

   0.31617   0.93993   0.73696
   0.49198   0.80143   0.96630
   0.73548   0.48046   0.85110

ans =  14
-verbatim

now with the pager

ans =

ans =  14


so it did the 7+7, but for some reason that was never echoed to the terminal.
Agreed, this is an odd use case, but I don't think this is intentional.
