xfer in doesn't show TSIG while xfer out does

[R Dicaire]

While testing TSIG zone xfers I came across the following:
The master server shows the zone was xferred out with TSIG, but the
slave server shows only that the zone was xferred in, no mention of
TSIG.

Is this normal?

My logging statements on both servers:

Server:
channel "myxferout" {
file "/etc/xferout.log" versions 4 size 1m;
print-time yes;
print-category yes;
severity info;
};

category "xfer-out" {myxferout;};

----------------------------------------------------------

Slave:

channel "myxferin" {
file "/etc/xferin.log" versions 4 size 1m;
print-time yes;
print-category yes;
severity info;
};
category "xfer-in" { myxferin;};
