its not the pl tone your gonna hear but instead its the generation of the tone for the pagers to open up for the beep / steady warning and audio of the call txmitted.
I may be misunderstanding that comment, but I think you missed the point. There are numerous systems that "strip" or disable the TX PL from the carrier when transmitting the paging tones. Since the PL tones and the QC tones are close in frequency range, this is done to keep the PL tone from mixing with the QC tones in the receiver audio and causing the pager to fail to respond.
Not all pagers are created equal, and some receiver audio sections don't resolve the audio well enough to discriminate the actual tone from the rest of the audio, so "stripping" the PL solves the problem. The result is that if you have PL enabled on that channel on your receiver, you don't hear the QC tones.
Not all receivers are created equal either, and one characteristic of some scanners and cheaper radios when PL is enabled on a channel where the PL is stripped during paging is a ticking noise at the beginning and end of each tone. The reason that occurs goes back to that inability to resolve the audio well enough coupled with the fact that the paging tones are several times the level of the PL tone, thus causing the audio/squelch circuit a little grief. It's not harmful, it just is what it is, as is the aforementioned low audio during tones, especially the higher ones, and especially when the tone levels are high enough to cause the receiver audio to clip the tones.
None of this means this effect is what the OP is actually hearing, it just means it is one of several possibilities.
