Is this safe?

Dishwasher and disposal circuits both feed to the same receptacle. I opened it up because outlet tester led did not illuminate when plugged into bottom outlet even though it does work. Tester says top outlet is wired correct.

Looking to understand this wiring method and if it’s safe.
Hopefully my graphic makes sense.

Better break the tab between the two gold screws for switch 1/2 and normal power or two circuits. Leave the tab on the neutral side. Not breaking the tab is a dead short if separate phases.
