You would want to set TASKB to be a systemd service unit that has both
After and BindsTo TASKA ( See the BindsTo documentation here:
https://www.freedesktop.org/software/systemd/man/systemd.unit.html#BindsTo=
).

You could even run this as a User service if it needs to run in the
context of the user (instead of system).
